The research activity of the Nano Bio-Spectroscopy group is at the interface of nanoscience, spectroscopy, and biomedicine. It focuses on the design of nanoscale tools acting as ideal interfaces to probe biological systems, at different scales. It relies on the elaboration of hybrid nanomaterials and their integration into theranostic agents or advanced “all optical” sensing devices for biological-related applications.

Research activities can be divided into two main topics:

Design of innovative nanoscale hybrid materials

Functional nanoscale hybrid materials are emerging as one of the most promising and rapidly expanding fields in materials chemistry. Our objective is to develop state-of-the-art technologies that will enable the elaboration of innovative hybrid nanomaterials for nanomedecine. We concentrate on the functionalization of plasmonic and magnetic nanoparticles using combination of aryl diazonium salt chemistry and controlled radical polymerization. Key experiments include plasmon-mediated strategies to achieve region-selective and multifunctional surface chemistry, in collaboration with ITODYS Laboratory (Université Paris Cité).

Advanced nanotechnology for drug delivery, diagnostic and theranostic

In recent years, interdisciplinary research on nanomedicine formulations, disease diagnosis and treatment has attracted much international attention as it offers unprecedented opportunities for personalized medicine. We develop in the group an integrated strategy, from the design of innovative multifunctional nanoparticles to the study of their properties and their use as therapeutic, prognosis or diagnostic tools, using Surface-Enhanced Raman scattering (SERS). We also develop nanoscale contrast agents for various optical imaging techniques, such as Raman and photoacoustic imaging, in order to enhance contrast in the NIR region, where tissue optical absorption is minimized. We provide them “smart” features, using thermo- or pH-responsive coatings, in collaboration with MSC Med (Université Paris Cité).
