In our laboratory of nanobiostructures (Nano Bio), we have developed original methods for synthesis of controlled size and shape of noble metal nanoparticles. We have developed interfacial nanofabrication methods including Langmuir-Blodgett technique (LBT), besides spin coating and auto-aggregation through adsorption or deposition on interfaces. Nanostructures are investigated by advanced spectroscopy (UV-Vis, ¹H NMR, FTIR, FT-Raman, ATR), X-ray diffractions, DSC calorimetry, and different surface methods (TEM, SEM, AFM and STM).
