Facilities & Labs

The scientific activities are focused on the physics and the chemistry of soft matter and on its applications in structured systems for advanced micro/nano-optics/photonics/fluidics.
New composite nanostructured materials are realized through bottom-up and hybrid bottom-up/top-down processes. Plasmonic materials, metamaterials and micro/nano structured materials, engineered by different methods, are fabricate and used in many fields, as energy harvesting, new sensing platforms and bio-medicine.
Our mission is to design, fabricate and characterize soft materials, including composites and hybrids, organic and biological. The manufacturing approach is twofold: firstly, nonlinear optics nano-microlithography is implemented in combination with micro-optical manipulation for realization of 2D / 3D structures made of polymer / nano-particles and integrable nano-structured micro-fluidic devices. Secondly, by a bottom-up approach, molecular self-assembling is exploited in order to get mesoscopic structures, from nanometer to micrometer scale, useful for optical and opto-fluidic applications.
Optical, structural and morphological properties are studied with the support of the thematic labs of our facility, where the most advanced investigation techniques are available: Ultrafast time-resolved IR-VIS multimodal non-linear optical spectroscopies, Ellipsometry, 2P Laser Scanning Confocal Microscopy integrated with an AFM system, Integrated Confocal Fluorescence Microscope / SNOM for simultaneous far and near field analyses, electronic microscopies (SEM, TEM), x-ray reflectometry (GID), optical micro-manipulation, SFA allowing for accurate measurements of inter-surfaces forces as small as 100 nN, with a Å-accuracy in the separation gap control, 250 sqm ISO 5 clean room supplied with thin film preparation and surface treatments equipment.
A large part of the research laboratories contributes to the CNR National User Facility Beyond-Nano – Polo di Cosenza and is accessible to external scientists by offering advanced research and technological services.

  • Jam session Nanotec… note di scienza su scala nanometrica

    Lecce, 27 settembre 2019 – ex monastero degli Olivetani “CAR-T: l’alba di una nuova era”  con: Attilio Guarini (IRCCS Istituto Tumori “Giovanni Paolo II” di Bari)  introduce e modera: Marco Ferrazzoli (Ufficio Stampa CNR Roma) a cura di: Gabriella Zammillo 

    Le CAR-T (Chimeric Antigens Receptor Cells-T) sono cellule modificate in laboratorio a partire dai linfociti T. Rappresentano una nuova strategia di cura che sfrutta il sistema immunitario per combattere alcuni tipi di tumore come linfomi aggressivi a grandi cellule e leucemie linfoblastiche acute a cellule B. Il prof Attilio Guarini, ematologo all’Istituto tumori Giovanni Paolo II di Bari, le definisce la “vis sanatrix naturae della antica medicina salernitana”, trattandosi del potenziamento dell’attività citotossica dei linfociti del paziente opportunamente ingegnerizzati per riconoscere e contrastare alcuni tipi di cellule tumorali.
