Synthesis of nanoparticles in solution with "green chemistry" methods. Strategies to obtain different porosities, dimensions and morphologies (nanospheres, nanocubes, nanorods, core@shell) of nanoparticles. Surface functionalization of inorganic nanoparticles. Chemical-physical analysis of nanostructures. Spectroscopic investigations : fluorescence, UV-vis-visible, NIR and infrared). Dynamic light scattering.

Laboratory (32-36 h)

1) Bottom up approach: synthesis of metallic nanoparticles (Au, Ag) in aqueous solution.
2) Top down approach: preparation of polymer nanoparticles
3) Functionalization
4) Spectroscopic characterization of the nanoparticles prepared in the optical field: UV-vis and and FTIR.
5) Investigation of colloidal properties.
