Optofluidics

Complex light beams realized by phase modulation techniques represent a versatile tool in several fields of optics as the material structuring at small scales and the optical manipulation of micro-objects. Soft matter based micro-particles, with controlled supramolecular structure, studied by implementation of optical trapping, lead to new opto-mechanical properties.

Structured light fields for optical control and manipulation

Methods to generate structured light fields are studied: light patterns and complex vectorial beams are realized by using optical phase modulation by means of polarization holograms. Taking advantage of the diffraction properties, the high efficiency, and the intrinsic achromaticity of the polarization holograms, the method overcome the limitations related to stability and efficiency, making it attractive for applications. These light fields coupled with photosensitive soft materials are used to investigate manifold new optical effects: perform materials structuring; design defects architectures in materials; optical manipulation of micro-objetcs.

Chiral microdroplets/microparticles optofluidics

Optical studies of chiral microparticles combine soft matter science with both photonics and optical manipulation. The particles are made by liquid crystalline polymer and are realized by controlling both the internal structure and the surface features. They constitute spherical microresonators suitable for several applications in photonics such as lasing. These microparticles enable the implementation of new strategies for optical trapping. Investigations on their opto-mechanical properties have shown that several kinds of optical manipulation (trapping, rotation and orbiting motion) are realized by means of the spin angular momentum transfer from photons to micro-particles.

Keywords: Photopolymerization; optical polarized and confocal microscopies; optical manipulation by complex beams

Berlino, 16 novembre 2018 

Alessandro Polini , giovane ricercatore presso l’Istituto di Nanotecnologia del Consiglio nazionale delle ricerche (Cnr-Nanotec) di Lecce, si è aggiudicato il Lush Prize 2018 categoria 'Giovani ricercatori', il premio che incoraggia le idee che promuovono la sperimentazione non animale.

Il giovane salentino ha visto così gratificare il suo studio basato sull’utilizzo di modelli 'organ-on-a-chip' altamente sofisticati per capire i meccanismi patologici alla base della Sclerosi Laterale Amiotrofica (SLA). Formatosi nel campo delle biotecnologie mediche, bioingegneria e nanotecnologie, anche con importanti esperienze internazionali -dal Lawrence Berkeley National Laboratory in California all'Harvard Medical School in Massachusetts per approdare poi alla Radboud University in Olanda- Alessandro Polini è rientrato in Italia per proseguire gli studi relativi ai sistemi 'organ-on-a-chip' grazie alla piattaforma tecnologica TecnoMED, il 'Tecnopolo di nanotecnologia e fotonica per la medicina di precisione' nato presso il Cnr-Nanotec di Lecce da un progetto finanziato da Regione Puglia, Cnr e Miur...
