Research activities
Nanoscale divided matter has a considerable developed surface. Problems related to the control of interactions at the interface become unavoidable when nanoparticles are used in complex environments such as biological media. Mastering nanoscale surface modification is also required in material science for which the surface chemistry impacts an assortment of physical properties.
My research, at the interface of chemistry and biology, focuses on the synthesis of hybrid mono/multifunctional NPs. My objectives are to define nanoscale surface modification strategies in the aim to address critical issues in fields related to nanotechnologies such as nanomedicine, bioimaging, plasmonic, metamaterials and smart materials, among others.
I currently develop three research topics :
1- Design of nanoparticles for biomedical applications :
Development of optimized PEGylation routes for intravenously administered long circulating NPs ; conjugation with biomolecules (antibodies and fragments, proteins, peptides, aptamers, nucleic acids, lipids) for bioimaging (MRI, NIR fluorescence imaging) ; development of nanocarriers (silica-based mesoporous NPs) for heat-triggered drug release induced under a magnetic field (magnetic) or near infra-red irradiation (plasmonic) ; Biofunctionalized magnetic nanoparticles for extracellular vesicles extraction and purification.
2- Surface chemistry for nanomaterial development :
Design of surface chemistry and coating strategies (SiO2, MgO, TiO2, Au,…) for the synthesis of multifunctional nanobuilding blocks used in extrinsic multiferroic ceramics ; plasmonic nanoresonators for metamaterials ; or used in the development of assembled nanomaterials (magnetic, plasmonic and/or ferroelectric).
3- Nanoparticles for Nano(eco)toxicology :
Tailor-made nanoparticles (Au, Ag, SiO2, TiO2) of controlled size, shape, physical surface properties (surface charge, HLB, hydrodynamic diameter) for toxicological studies ; NP labelling for tracking from cellular level (internalization) to tissues (translocation) and to the whole animal model (biodistribution) ; Colloidal stabilization in complex media (natural aquatic systems, physiological media…).
