The research activities of the Nanoscience laboratory include three main fields: nanophotonics, characterization of nanostructured materials, and nanobiotechnologies.
Nanophotonics. Photonics at the nanoscale allows understanding new phenomena which could bring up new devices. Nanocrystalline semiconductors will be studied to enable new functionalites such as amplifiers and lasers. Then by using e-beam lithography two and three dimensional photonics crystals will be produced and characterized. Integrated silicon photonics will be studied with emphases on optical switches, modulators and optical gates. The coupling of nanocrystalline materials with photonic crystals allow to develop innovative devices which could be used as biosensor or biotransducers.
Characterization of nanostructured materials. New functional materials, such as ionic compounds or semiconductors, are key to innovative applications in energetic, micro and optoelectronics. Among the various materials, nanostructured materials with properties which are critical depending on their structures are basics to these developments. Since a few years, we are performing an experimental activity on nanostructured composite by using vibrational spectroscopies (Raman and FT-IR). Mainly nanostructured metals, and quantum dots of oxide or semiconductors in dielectrisc have been studied. Recent activities concern the study of carbon nanotubes.
Nanobiotechnologies. The general aim of this activity is to conceive and experiment new nanodevices, designed at the atomic level, to master their functionalities controlling their three dimensional geometry. Since some of these properties are peculiar to bio molecule whose function is related to their self-regulated 3D structure, the insertion of bio molecules in nanometric structures, such as quantum dots, allows to obtain new classes of nanodevices which acts as nanosensor or nanotrasducer or nano photo activator. This research is interdisciplinary among biochemists, materials scientists, electronic engineers. We are currently developing an optical nanosensor based on silicon to recognize pathogenic species (viral and DNA) and a nanosystem photoactuated.
