Plasma Physics and Technologies

This research area deals with theoretical modelling, experimental applications and diagnostics of plasma.
Elementary Processes in Plasmas are studied by accurate theoretical methods, relating to different classes of processes relevant to many technological fields, from thermonuclear controlled fusion (negative ion sources, divertor region in tokamak), to aerospace (re)entry conditions and astro-chemistry. Thermodynamic and transport properties in equilibrium plasmas have been calculated for complex gas mixtures, of different atmospheres (Earth, Mars and Jupiter). Space Plasmas are typically in very extreme conditions, from very low to very high density: this is the case of dusty plasmas, which deals with the dynamics of dust above airless body surfaces, rings and planet formation. Electric thrusters (Hall-effect and helicon discharges) and plasma-assisted combustion (SCRAMJET) are important for space transportation (satellite guidance, orbit transfer and deep space exploration).
The study of the temporal and spatial evolution of Laser Induced Plasma in different environments by spectroscopic techniques gives the required knowledge useful for a wide range of application fields (e.g. chemical analysis applied to environment, cultural heritage, space, material processing). Theoretical investigations have been also dedicated to verify the assumption of local thermodynamic equilibrium (LTE), commonly considered for calibration-free LIBS.
Plasma sources based on discharges created by direct current, capacitively coupled radiofrequency, inductively coupled radiofrequency and microwaves are characterized by thermal non-equilibrium condition and are modelled by kinetic approaches: polynomial expansion, state-to-state and particle-based (Particle-in-Cell, Monte Carlo and Molecular Dynamics) methods. These plasmas are studied from an experimental point of view, employing different optical techniques for Advanced Non-Equilibrium Plasma Diagnostics.
In particular Microwave Plasmas are employed successfully for the growth of undoped nanocrystalline (NCD) and polycrystalline diamond (PCD) films, deposited by a microwave PECVD (MWPECVD) technique starting from gas mixtures of CH4 highly diluted (less than 5%) in Ar and H2, respectively.
Plasma surface engineering includes a large area of processes aimed to drastically change the surface properties of materials preserving the bulk ones. The processes can be performed by using both low and atmospheric pressure plasmas, in both direct and remote approach, injecting the film precursors in gas, vapor and aerosol form.

    Plasma technologies for materials & surfaces

    Plasma surface engineering embraces a large range of processes aimed to drastically change the surface properties of materials preserving the bulk ones. This includes for instance corrosion protective coatings, barrier layers for food packaging, surface hydrophobization/hydrophilization, enhanced surface dyebility/printability or adhesion. In particular plasma-assisted deposition can be used to produce films on a solid material by promoting chemical reactions at the plasma/substrate interface. Indeed, by using sacrificial layers/substrates free standing nano-films can be produced. The processes can be performed by using both low and atmospheric pressure plasmas in direct and remote approach, injecting the film precursors in gas, vapor and aerosol form.

    Plasma reactors design

    Low pressure plasma reactor design involves matching of sample/chamber size, gas flow rate/pumping speed, electrodes potential distribution and power sources. Furthermore, often heating/chilling of electrodes or substrates is necessary, as well as bias, to control surface ion bombardment. Technologies implemented by plasmas are: PECVD, remote plasma MOCVD, sputtering, etching, plasma MBE.

    Atmospheric pressure dielectric barrier discharge reactors for surface treatment of materials need a smart design, assembly and optimization. Reactors design and electrode configurations are tailored to address the requirements of specific plasma processes (e.g., deposition of thin films from precursors in vapor or aerosol form) and, importantly, the shape and dimension of the substrate to be treated. Atmospheric pressure reactors include also plasma jets, i.e., remote plasma sources in which the plasma is allowed to exit from the region where it is generated and to propagate in the external environment towards the substrate to be treated.

    Plasma Surface Engineering

    Strategies differ depending on the addressed surface property. Typically both low and atmospheric pressure plasma processes can be carried out.

    Barrier and protective coatings consists in inorganic film (SiOx or SiNx) commonly deposited from organosilicon fed plasmas.

    The control of polymer adhesion properties and alike (dyebility) can be reached by grafting of polar groups (oxygen or nitrogen containing ones) in plasma fed with O2, N2 or H2O.

    Hydrophobization can be achieved either by PECVD of fluorocarbon and organosilicon coatings or by grafting of F-contaning functionalities (e.g., CF4-fed plasma)

    Plasma processing of 3D materials and powders

    Plasma treatment of complex three-dimensional (3D) porous materials (membranes, scaffold, fabrics, etc.) for fine tuning of the surface chemistry of the outer and inner regions of the substrates, while leaving the porous architecture intact. The activity includes also the plasma surface functionalization of powders and granules for several applications in the field of catalysis, absorbing materials, biomaterials, etc..

    Strategies

    Low pressure and atmospheric pressure PECVD, plasma grafting of functional groups and plasma sputtering of metal and metal/oxide carried out both in direct and remote approach. Reactors design and electrode configurations are fitted to the specific shape and dimension of the substrates to be treated.

    Lecce, 6 settembre 2017 

    Lo European Research Council, che promuove la ricerca di eccellenza in Europa, nei giorni scorsi ha reso noti i nomi dei 406 vincitori della selezione ERC STARTING GRANT 2017, il bando tra i più competitivi a livello internazionale.

    Su 3085 progetti presentati, 406 i progetti selezionati a cui sono stati destinati i 605 i milioni di euro di investimento. 48 le nazioni di provenienza dei ricercatori, soltanto 17 gli Italiani che condurranno le loro ricerche nel nostro paese, tra cui Loretta del Mercato, ricercatrice dell'Istituto di Nanotecnologia del Consiglio Nazionale delle Ricerche di Lecce.

    Un importante riconoscimento alla ricerca nel settore della medicina di precisione condotta presso il CNR NANOTEC, un indiscusso premio al talento della giovane ricercatrice che, a 38 anni e un contratto a tempo determinato, sarà a capo del progetto "Sensing cell-cell interaction heterogeneity in 3D tumor models: towards precision medicine – INTERCELLMED".

    Il progetto, il cui obiettivo è affrontare uno dei problemi più spinosi della ricerca sul cancro, ovvero la difficoltà nel trasformare i risultati delle ricerche scientifiche in applicazioni cliniche per i pazienti e che vedrà coinvolto l'Istituto tumori "Giovanni Paolo II" di Bari, si propone di sviluppare nuovi modelli in vitro 3D di tumore del pancreas, alternativi ai modelli animali, ingegnerizzati con un set di sensori nanotecnologici che consentiranno di monitorare le interazioni delle cellule tumorali con il loro micorambiente, verificare l'appropriatezza delle terapie prima della somministrazione ai pazienti oncologici e quindi prevedere la risposta dei singoli pazienti ad una o più terapie antitumorali.

    La realizzazione di queste piattaforme 3D multifunzionali consentirà di superare le evidenti differenze intercorrenti tra "modelli animali" ed esseri umani fornendo dati attendibili ed in tempi più rapidi rispetto ai dati ottenuti tramite lunghi e costosi procedimenti di sperimentazione sugli animali. Le tecnologie e i modelli sviluppati saranno estesi anche ad altre forme di tumori solidi nonché impiegati per studi nell'ambito della ingegneria tissutale e della medicina rigenerativa.

    Nanostructures & Self Assembling

    Nanomaterials are coming into use in healthcare, electronics, cosmetics, catalysis and other areas, because they bring novel  mechanical, electrical, thermal, optical, electrochemical, catalytic properties differing markedly from that of the component materials.

    Nanostructures are not simply another step in the miniaturization of materials. They often require very different production approaches. There are several processes to create nanomaterials, classified as ‘top-down’ and ‘bottom-up’., which are explored at Nanotec.

    Self-Assembled Monolayers (layers that are one atom or molecule deep) are also routinely made and used in chemistry. The formation and properties of these layers need to be understood from the atomic level upwards, even in quite complex layers (such as lubricants). Advances are being made in the control of the composition and smoothness of surfaces, and the growth of films.

    Furthermore, engineered surfaces with tailored properties such as large surface area or specific reactivity are used routinely in a range of applications such as in fuel cells, sensing and catalysts. The large surface area provided by nanoparticles, together with their ability to self assemble on a support surface, could be of use in all of these applications. Main topics in the focus are:

    1. Metallic Plasmonic Nanosystems
    2. Molecular Architectures at Interfaces
    3. High Charge Mobility Columnar Mesophases
    4. Organic/inorganic Nanocomposites
    5. Nanotextured Materials

    Metallic Plasmonic Nanosystems

    Research topics:

    1. Design, growth and investigation of plasmonic nanostructures coupled to semiconductors, ceramics, glass and plastics by MBE, thermal evaporation and plasma sputtering
    2. Synthesis of plasmonic systems alternative to nobel metals
    3. Design and synthesis of novel multifunctional multi-metallic core-shell nanoparticles supported on various substrates combining plasmonic/catalytic (e.g. Ag/Pd) and plasmonic/magnetic (e.g Au/Co) functionalities
    4. Development of Biochemical sensing exploting SERS mechanism
    5. Design of Enhanced light-matter interaction coupling semiconductors
    6. Tailoring of surface energy of support at the interface nanoparticle/substrate to tune nanoparticle shape and plasmonic response
    7. Post growth processing by annealing and plasmas to tailor optical and plasmonic properties
    8. Development of system for liquid and phase-change plasmonics
    9. Exploitation of plasmonics in localized catalysis

     

    Molecular Architectures at Interfaces

    The interfaces between bulk media are often site of reactions and phenomena which are distinct from the bulk substances and frequently dominate the macroscopic properties of the entire system. Understanding how molecules adsorb and react with these surfaces has potential applications in industrial processes and everyday life. Catalyses, combustions, lubrication, adhesion, wetting, electrochemical reactions are only few examples of phenomena of industrial interest which are governed by interfacial properties. Polymer surfaces and interfaces play an increasingly important role in modern electronic and optoelectronic technologies (i.e. organic transistors, OLED), as well as in biomedical applications (i.e., biocompatibility). Surface-specific IR and visible sum-frequency generation (SFG) vibrational spectroscopy is a powerful and versatile in situ surface probe which permits identification of surface molecular species and provides information about orientation of functional groups at the surface. SFG is non destructive, highly sensitive, and has good spatial, temporal, and spectral resolution. Because the technique works in real time under water and protein solutions it is also very well suited for studying biomaterials and biointerfaces.

    A) In SFG experiment, pulsed VIS and IR laser beams overlapping at an interface produce a nonlinear polarization density and hence a coherent output beam at the sum frequency . B) Resonant enhancement and beams polarization dependence of the active vibrational modes of molecules provide orientation of the moieties and the molecular architecture at interface

    High Charge Mobility Columnar Mesophases

    Molecularly organized supramolecular materials are promising candidates for applications in organic opto-electronics since the properties of functional materials can be enhanced when they have a well-organized internal structure. Within this frame, the ability of liquid crystals to self-organize in mesophases to obtain functional architectures is frequently exploited and, in particular, the properties of columar liquid crystals are exploited since they are able to stack spontaneously into columns to give one-dimensional structures of π-conjugated organic molecules. This organization reflects in a long-range π-orbital overlap that allows, after suitable charge injection, intracolumnar charge carrier mobilities with high values comparable to those of amorphous silicon. These properties make columnar liquid crystals very attractive materials for use as organic semiconductors.

    Strategies

    Study and characterization of novel columnar liquid crystal based on innovative molecular and supramolecular architectures ;

    Studies of discotic mesophases whit ambipolar electrical conductivity;

    Development of high mobility columnar mesophases with suitable mechanical and physical properties for application in devices (OFET, Photovoltaics etc.)

    Organic/inorganic  nanocomposites

    Organic-inorganic nanocomposites consisting of metal or metal oxide nanoparticles embedded in an organic matrix combine unique properties offered by both organic and inorganic components on a nanoscale level and are, therefore, attractive materials for a large number of applications in the field of catalysis (e.g., Pt, ZnO, TiO2), sensing, optical filters, antibacterial metal (Ag, Cu) delivery systems, plasmonic devices.

    Strategies

    1. One-step simultaneous metal sputtering and plasma polymerization from a suitable monomer forming the embedding matrix. This approach, carried out in reactor as TRIMAG is particularly appealing since it is possible to independently change the precursor of the matrix (CFx, CHx, SiOx,…) and the metal target (Au, Pt, Ag, …) producing different nano-composite coatings with tunable metal content.
    2. Nanocomposite coatings containing Metal oxide nanoparticles can be prepared in low pressure reactors as TRIMAG (link a TRIMAG in URT Facilities) using the oxide target or the metal one, in a O2 containing plasma.
    3. Inorganic nanoparticles/polymer nanocomposite coatings are prepared by an atmospheric pressure dielectric barrier discharge fed with the aerosol of a dispersion containing preformed NPs and the  precursor of the organic matrix.

    Nanotextured materials

    Plasma nanotexturing is a quite fast method to address biomimetic properties to simple raw materials such as polymer or glass.  It can be driven via bottom up approach or a top down one: in the first case the adsorbed precursors can organize in a hierarchical way leading to  a micro/nanotextured coating, in the latter subtractive etching, assisted by the random arrival of inhibitors,  leads to the formation of pillars. After nanotexturing, the chemistry of the surface can be tuned by a suitable plasma deposited coatings, to become more hydrophobic or hydrophilic or functionalized. Nanotextured surfaces give access to unique properties such as water and oil repellency, antireflectivity (moth eye effect), superhydrophilicity and anti-fog.

    Strategies

    1. Nanotexturing of surfaces can be obtained by plasma rough etching of polymers with O2 fed plasma or in the case of silicon based materials (Si, SiO2 but even silicone) with fluorine producing plasmas
    2. transfer of a pattern produced by exposing a micro-featured (i.e. TEM copper grid) or nano-featured mask (i.e. colloidal lithography)
    3. deposition of teflon-like coatings in soft plasma conditions (i.e. modulated/pulsed discharges)
    4. aerosol-assited cold plasma deposition of nanocomposite coatings consisting of inorganic nanoparticles embedded in an organic matrix and showing hierarchical multiscale surface texture.

      International Workshop on Micropropulsion and CubeSats

      Bari, Italy, 26 – 27 June 2017

      Program – MSC2017

      This narrow-field, invited-only meeting is the first attempt to bring together the Materials and Micropropulsion communities with a view to contribute to the development of the Global Materials and Micropropulsion Roadmap, and set such meetings to a regular basis.

    Graphene & Other 2D – Materials

    The work on Graphene and related 2D layered materials in the Apulian Graphene Lab at CNR-NANOTEC institute is addressed minly to the development of methodologies of Production and Material Processing. We also develop simple devices  for the assessment of the potential applications and for the validation of the materials properties.

     

    2D- MaterialsACTIVITIES

     

    Graphene production is performed by CVD on copper, CVD-graphene, (large are growth up to 300 cm2) and by SiC sublimation, Epitaxial-graphene, (graphene on SiC wafer up to 1” diameter) on Si-face (mono and bilayer graphene) and on C-face (few layers graphene).

     

    2D layered materials synthesis. With an expertise of decades of research in the CVD technologies, we are working on the development of efficient processes for the growth of transition metal dichalcogenides (MoS2, WS2); the goal is the growth of single- and few-layer materials on graphene as well as on other epitaxial substrates (van der Walls growth) for the optoelectronic applications.

     

    Graphene Material Processing  is on methodologies for graphene transferring on different substrates (glass, silicon and plastic) and on wet and dry procedures for doping and functionalization of single and multilayer graphene. Here, our expertise is on the plasma processing of graphene for the production of graphane, fluorographene and graphene oxide, thus tailoring properties to explore new applications in optoelectronic, sensors, energy and biotechnology.

     

    Graphene Characterization,  graphene-based materials are characterized and investigated at the nanoscale by optical spectroscopy (Raman, Ellipsometry) and electrical measurements (Van der Pauw, Hall).

     

    HIGHLIGHTS

    The research activity within the Apulian Graphene Lab, have already achieved important breakthroughs inside the EC project MEM4WIN on Smart Windows. Examples are:  the production of high quality graphene layers on large area with a sheet resistance lower than 15 Ω/square and, reliable plasma-chemical methods designed for surface functionalization of graphene.

    Multifunctional Oxides & Smart Coatings

    A wide range of metal-oxides exhibit intriguing properties and multiple functionalities. These materials are the subject of many experimental and theoretical studies, since they have found broad applications in different fields from microelectronics to catalysis, energy saving and production. At the same time, the sensitive nature of chemical and physical properties of metal-oxides to the microstructure and interfaces has created challenges and opportunities to materials and physics research communities. Synergistic research efforts of material growth, processing, characterization, and theoretical modeling of microstructures and properties are active in the following topics:

    1. High-K and dielectrics
    2. Transparent conductive oxides, TCOs
    3. Smart coatings

    Oxides (high-K, ceramics and TCOs)

    Exploitation of oxides thin films and nanoparticles (ZnO, In2O3, NiO, Er2O3, high-K, TCOs,..) requires growth optimization and study of their magnetic, optical and electrical properties as well as elucidation of the correlation structure-nanodimension-properties-functionlity. To this aim, activities are focused on:

    1. Developing and understanding novel MOCVD and plasma growth processes to improve materials quality, also through the synthesis and testing of novel MOCVD growth precursor
    2. Optimization of oxides growth by plasma oxidation and sputtering processing. Various plasma configurations (remote plasma, radiofrequency, ECR, ..) are investigated.
    3. Post growth processing by annealing and plasmas to tailor optical and electrical properties
    4. Oxide surfaces functionalization for diverse areas of applications in catalysis, corrosion, gas sensing, and micro- and optoelectronics.
    5. Design, growth and optimization of new transparent oxide and nitride based thin films and multilayers with tuned optical and electrical properties.

    Our strategy for materials and processes optimization is based on the exploitation of

    In-situ real time multidiagnostics to control and understand reactions kinetics and dynamics in gas phase as well as on the surface of the growing oxide.

    Th3e in-situ measurements are corroborated by extensive characterization by XRD, AFM, SEM, XPS, Raman spectroscopy, conductivity measurements.

    Representative achieved results can be summarized as:

    1. Plasma assisted MOCVD processes for depositing novel Er2O3, HfO2, and ZnO thin films and nanostructures with tailored optical and electrical properties
    2. Analysis and tailoring of interfaces in perovskite oxides based heterojunctions
    3. Charge and sheet resistance tailoring in TCOs through post-growth processing
    4. Optimization of ITO microstructure and conductivityby remote plasma processing

     

    Smart Coatings

    Smart coatings are capable of adapting some properties dynamically to an external stimulus in its environment (i.e. pressure, light, heat, etc.,) and react in a predictable and possibly reversible fashion. Potential applications of such coatings is in various research fields including controllable biofuel cells, bioelectronic devices, stimuli responsive biosensors and biomaterials, drug delivery.

    Strategies used to advance research in the field consist of:

    1. pH-responsive coatings- co-deposition by low pressure plasma enhanced vapour deposition fed with acid and/or basic precursors.
    2. Pulsed plasma of NIPAM and alikes can lead to Thermoresponsive coatings.
    3. ZnO- or TiO2-containing coatings showing changes in water contact angle upon UV light irradiation. The coatings are deposited using aerosol-assisted plasma processes in which dispersions of ZnO or TiO2 nanoparticles are injected in aerosol form in the atmospheric plasma

      International Workshop on Micropropulsion and CubeSats

      Bari, Italy, 26 – 27 June 2017

      Program – MSC2017

      This narrow-field, invited-only meeting is the first attempt to bring together the Materials and Micropropulsion communities with a view to contribute to the development of the Global Materials and Micropropulsion Roadmap, and set such meetings to a regular basis.

    Inorganic Semiconductors

    Our objective here at CNR-Nanotec is the development of new semiconducting materials and nanostructures representing the foundation of more efficient, high performance, low power consumption optoelectronics and micro/nanoelectronics devices. To that purpose, we comprehensively study and engineer growth dynamics and structural features in inorganic semiconducting compounds of different families, to enable innovative optical, magnetic and electronic properties which can be applied to the fields of photonics, electronics, sensing, or biotechnology. A wide range of materials and related applications is covered by the center, thanks to the availability of material-driven facilities and to the close synergy with the other platforms of the institute and with external national and international collaborations.

    The main topics are:

    1. III-N Heterostructures
    2. III-V Semiconductors
    3. Si-based thin Films and Its Alloys

    III-N Heterostructures

    Gallium nitride, GaN, ant its alloys with aluminum, AlGaN, and indium, InGaN, and the quaternary InGaAlN represent a class of semiconductors with properties of wide and direct band gap (tunable from the deep UV to the NIR), high break-down voltage, large critical electric field, and high thermal conductivity. Applications of these compounds encompass next generation of high frequency/high power transistors and optoelectronics devices, such as deep-blue and ultraviolet LEDs, lasers and photodetectors. Furthermore, the chemical and mechanical robustness of these compounds allows operation in harsh conditions, thus opening several possibilities for sensing in drastic environments. Our III-Ns technology is  based on metal organic chemical vapour deposition (MOCVD) growth combined with suitable nanofabrication tools  of Chlorine-chemistry deep etching and deep UV optical lithography.

    Research topics:

    1. Create recipes for oxide removal and substrate preparations enabling better control of the surface in initiating epitaxy on various substrates (sapphire, SiC, Si, GaN, oxides-ZnO, LAO,..)
    2. Develop and understand growth processes to improve materials quality
    3. Growth of high Al-containing (and high-In) III-N Materials (InAlN, AlGaN, InAlGaN,..)
    4. Increase the IQE of blue and green InGaN HB-LEDs via the use of quantum heterostructures fabricated on the non-polar a- and m-planes

    Strategies

    1. Development of new processes combining MOCVD and MBE with plasma technologies
    2. Processing and modulation of interfaces in multilayer structures
    3. In situ real time multidiagnostics approach to control and understand growth processes
    4. Investigating the process-properties-functionality interplay through extensive characterization

    III-V Semiconductors

    Our research aims at enlarging the current palette of technological semiconductors with new alloys and quantum confined nanostructures to respond to the continuous need of new materials with tunable properties that add flexibility to the design  and performance of optoelectronic and electronic devices.

    Research topics:

    1. Investigation of relevant growth mechanisms by molecular beam epitaxy (MBE) governing the formation of self-assembled InAs/GaAs quantum dots (QDs) and their structural properties for applications in photonics, telecommunications and solar cells.
    2. Novel growth strategies for the Bi-containing  semiconductors of GaAsPBi, GaAsSbBi, which are  exciting candidates for next generation optoelectronic and  spintronic devices
    3. MOCVDgrowth of nanostructures of InN, InP, by VLS (Vapour-Liquid-Solid phase Epitaxy)
    4. III-Vs (GaAs, InAs, InP, GaP) surface functionalization towards achieving biological and chemical sensing applications

    Si-based thin Films and Its Alloys

    Silicon, in all its forms of crystalline, microcrystalline, nanocrystalline and amorphous is the foundation of the microelectronics and photovoltaics. Capabilities of silicon can still be enlarged by “bandgap enginnering” using Si-based alloys such as silicon germanium (Si:Ge), silicon carbon (Si:C) providing a tunable band gap from <1eV for Si:Ge to >2.5eV for Si:C extending to dielectrics of silicon nitrides Si:N and silicon dioxide SiO2. The research covers the synthesis, characterization, modelling, device performance in different fileds, photovoltaics, electronics.

    Research topics:

    1. Plasmochemical deposition of amorphous and microcrystalline silicon by PECVD using SiF4-H2-He and SiH4-H2-He as precursors
    2. PECVD deposition assisted by Sputtering of nanostructured Er-doped Si thin films
    3. Study of their optical, compositional and electrical properties and correlation between bonding configuration, growth dynamics, film nanostructure and optical properties

    Strategies:

    1. Development and understanding of plasma processes in order to improve materials quality
    2. Processing of substrates and optimization of interfaces in multilayer structures
    3. Optimization and understanding of the correlation between the nanostructure and optical properties for the optimization of devices
    4. In situ real time multidiagnostics approach to control and understand growth processes.

    Materials

    NANOTEC is engaged in various aspects of materials research for advanced applications. Research activities are focused on growth and synthesis with various physical and chemical methodologies (CVD, MOCVD, MBE, PVD, PECVD, self-assembling, sol-gel, etc); based on fundamental research, we elucidate principles underpinning processing-structure-property relationships in functional materials and nanomaterials both inorganic and organic, and their hybrids and nanocomposites, with interesting electronic, magnetic, optical, mechanical or catalytic properties; we exploit those relationships to introduce new functionalities in materials science and build a basis for “predicting” new materials based on the established principles. Topics covered include III-V semiconductors, Si-based alloys, organic semiconductors, dielectrics, piezoelectrics, ferroelectrics, nanomaterials, graphene, 2D-materials, nanocomposites, colloidal nanocrystals, non-crystalline solids, self-assembled monolayers and functional surfaces. Through these efforts, NANOTEC aims to create advanced materials that contribute to society functional innovations.

    Loretta del Mercato, si aggiudica  l'ERC STARTING GRANT 2017

    uno dei bandi più competitivi a livello europeo.

    Lecce, 6 settembre 2017 

    Lo European Research Council, che promuove la ricerca di eccellenza in Europa, nei giorni scorsi ha reso noti i nomi dei 406 vincitori della selezione ERC STARTING GRANT 2017, il bando tra i più competitivi a livello internazionale.

    Su 3085 progetti presentati, 406 i progetti selezionati a cui sono stati destinati i 605 i milioni di euro di investimento. 48 le nazioni di provenienza dei ricercatori, soltanto 17 gli Italiani che condurranno le loro ricerche nel nostro paese, tra cui Loretta del Mercato, ricercatrice dell'Istituto di Nanotecnologia del Consiglio Nazionale delle Ricerche di Lecce.

    Un importante riconoscimento alla ricerca nel settore della medicina di precisione condotta presso il CNR NANOTEC, un indiscusso premio al talento della giovane ricercatrice che, a 38 anni e un contratto a tempo determinato, sarà a capo del progetto "Sensing cell-cell interaction heterogeneity in 3D tumor models: towards precision medicine – INTERCELLMED".

    Il progetto, il cui obiettivo è affrontare uno dei problemi più spinosi della ricerca sul cancro, ovvero la difficoltà nel trasformare i risultati delle ricerche scientifiche in applicazioni cliniche per i pazienti e che vedrà coinvolto l'Istituto tumori "Giovanni Paolo II" di Bari, si propone di sviluppare nuovi modelli in vitro 3D di tumore del pancreas, alternativi ai modelli animali, ingegnerizzati con un set di sensori nanotecnologici che consentiranno di monitorare le interazioni delle cellule tumorali con il loro micorambiente, verificare l'appropriatezza delle terapie prima della somministrazione ai pazienti oncologici e quindi prevedere la risposta dei singoli pazienti ad una o più terapie antitumorali.

    La realizzazione di queste piattaforme 3D multifunzionali consentirà di superare le evidenti differenze intercorrenti tra "modelli animali" ed esseri umani fornendo dati attendibili ed in tempi più rapidi rispetto ai dati ottenuti tramite lunghi e costosi procedimenti di sperimentazione sugli animali. Le tecnologie e i modelli sviluppati saranno estesi anche ad altre forme di tumori solidi nonché impiegati per studi nell'ambito della ingegneria tissutale e della medicina rigenerativa.
