This project aims at developing scaffolds made of silk proteins to detect pollutants in water or air. Various systems (hydrogels, foams or electrospun filters) made from silk fibroin will be prepared incorporating metallic nanoparticles. These composites will allow to strongly concentrate organic pollutants and thanks to the presence of plasmonic nanoparticles will be used to detect them in situ by Surface Exalted Raman Spectroscopy (SERS) techniques.

Stage M2S2 "Raman-based characterization of functionalized graphenoid surfaces"
Self-assembly of molecular networks has emerged as a versatile and promising approach to tune the surface properties of materials. The aim of this study is to use Raman spectroscopy to investigate the electronic structure of graphenoid surfaces functionalized with 3D molecular building blocks and confirm the presence of metal-ligand coordination bonding. In this context, an electronically active molecule can be decoupled from a conducting substrate, with a view to develop new molecular electronics and photonics devices
