Issam Kherbouche soutiendra sa thèse intitulé :

" Plasmon-mediated surface grafting as a novel approach for the next generation of nanodevices "

le mardi 3 Décembre 2019 à 10h00 , à l'Université Paris Descartes, Salle des thèses (5ème étage, bâtiment Jacob).

The current development in nanotechnologies requires more than ever nanostructures with smart and controlled surfaces. Plasmon-mediated surface chemistry offers an unprecedented fast and cheap large scale ‘bottom-up’ approach that uses the nano-localized plasmonic properties surrounding nanostructures, to trigger site-selective surface functionalization and place molecules/nanomaterials into specific reactive spots. When combined to diazonium salt chemistry , this plasmon-mediated strategy offers the possibility of renewing the toolbox of surface chemistry approaches by: (i) controlling the nanoscale localization of surface molecular functionalities derived from diazonium salts; (ii) regulating the thickness of polymer grafts as well as their composition and growth orientation; (iii) positioning functional molecules/nanomaterials on highly reactive regions (reactive spots) or high EM field regions (hot spots), while keeping most of the nanostructure surface chemically passive. This approach will not only pave a new way for the nanoscale multi-functionalization of plasmonic nanoparticles but will also provide a general strategy to attach molecules to hot spot regions and further improve their SERS detection and analysis for (bio)sensing applications.
