Abstract: Organic semiconductors in different shapes and composition can be interfaced with living cells. This provides a new, exciting route towards optical control of physiological functions or the restoring of natural functions. In this talk I will present a number of experiments that show the effective abiotic-biotic coupling with cells and small animals, suggesting the potential of organic light actuators for geneless opto stimulation. Investigated systems are based on carbon molecules or polymers as photoactive component in planar films, nanostructured layers or nanoparticles. Spectroscopy, photo-electrochemistry and photo-electrophysiology are exploited to carry out the experimental investigations. While the mechanism explaining such coupling is still unknown, it is appering that thermal, capacitive, faradaic or chemical coupling are all options to be carefully evaluated. To conclude the successful use of an organic retina implant for restoring visual acuity in blind animals will be reported.
Bio: GL research activity regards the science and technology of nanostructured and molecular materials. The main area of experimental work is photophysics, for application in energy, bio-photonics, neuroscience and medicine. In particular, he is recently involved in the project for developing an artificial retina prosthesis. The activity produced 300 papers in international journals, 190 invited talks at international conferences and five patents. He is involved in two start-up companies. He is the author of the book “The Photophysics behind Photovoltaics and Photonics” for Wiley-VCH.
