Umberto Martino soutiendra sa thèse intitulé :

" Design of plasmonic Janus gold-silica nanoparticles for surface enhanced Raman spectroscopy "

le vendredi 22 novembre à 14h dans la salle 774 ( Bâtiment Lavoisier)

During the last decade, Surface-enhanced Raman scattering (SERS) has become a major vibrational spectroscopic technique moving fast towards areas of biology, forensic science, analytical chemistry, art and conservation science. Despite the huge advances in the field, the controlled assembly of anisotropic plasmonic nanoparticles (NPs), remains challenging for the production of long-term stable NPs assemblies in suspension and requires time-consuming and complex purifications techniques. We investigated in this project a new  approach for the controlled dimerization of plasmonic Janus anisotropic nanoparticles into highly SERS-active substrates in order to improve the yield and purity of cluster composition.
