The Laboratory of Nanotechnology, Instrumentation and Optics (LNIO) at the University of Technology of Troyes is tasked with the development of nano-optics. The group research focus areas are: plasmonics, integrated optics, optoelectronics, new spectroscopies and microscopies, multiphysics modeling, multi-functional nanosensors, nanobiophotonics and nanomaterials for photonics, photochemistry and photophysics.
The axes of research involved in the COST are:
- Nanospectroscopy (Prof. Pierre-Michel Adam)
Activities in this area concern the fundamental study of light emission from nano-objects and the associated linear and non-linear processes. Studies focus in particular on radiative and non-radiative transfers between metal nanoparticles and molecules.
- Molecular plasmonics and nanophotochemistry (Prof. Jérôme Plain)
Projects in this field involve the study of local interactions between plasmonic nanosources and photosensitive molecular systems. Plasmonic systems (nanosources, nanoantennas, etc.) and photosensitive organic materials are manufactured and characterized. Research objectives include the development of active plasmonic systems, hybrid nanomaterials and molecular probes.
- Nanobiophotonics (Dr Rodolphe Jaffiol)
he general issue addressed here is the organization of the membrane of living cells on the sub-micrometer scale. Researchers are developing imagery and spectroscopy tools dedicated to biophysics applications, such as Fluorescence Correlation Spectroscopy (FCS) in volumes of nanometric size.
- Nanomanufacturing (Dr Anne-Laure Baudrion)
Efforts are geared to producing nano-objects and nanostructured materials for nano-optics on the basis of two complementary approaches: top-down, using e-beam or optical lithography, RIE etching, etc.; and bottom-up, using chemical synthesis, self-assembly, surface functionalization, etc.
