[2008 - present] ∎ Gold Nanoparticles for Plasmonics and Health


Our activity focuses on the synthesis and assembly of high quality colloidal gold nanoparticles (Au-NP), whose morphologies (sizes, shapes) and coatings are optimized to generate light, heat or charge carriers, depending on the targeted application. Indeed, the hybrid nanoparticles (NP) that are composed of a plasmonic-metal nanoparticle (such as gold, silver, copper,...) and another component wich can be a molecule, a semiconductor, a Qdot, a catalyst.. have a strong technical and societal impact on Energy, Environment and Health (research field of the CEA-NIMBE). After 20 years dedicated to the study of photo-induced processes in molecular sytems, the main objective of our research is now to take advantage of the light-matter interaction in highly controlled gold nanohybrids. This research is carried out in the framework of very stimulating collaborations,  with expert teams  (see below the list of funded coll.) to discover unexpected properties.

[1988 -2008] ∎ Photophysics and Photochemistry (20 years)

Interface experience / theory

S. Marguet obtained a permanent research position in 1993 after a PhD at the interface experience/theory (J.C. Mialocq, P. Millié), followed by a post-doc in the field of pulse radiolysis (P. Neta, NIST, USA). By combining “time-resolved optical spectroscopies” and quantum chemistry, she was involved in two main projects :

  • [1993 - 2001] : Photophysics of Organized Molecular Systems.
  • [2001 - 2008] : Interaction of UV radiation with DNA

During this 20 year period, she had the opportunity to study many photoinduced chemical reactions  and have developed an expertise of energy transfer and electron transfer in molecular systems, working with the assistance of many researchers : Ph. Millié, D. Markovitsi, T. Gustavsson, M.A. El-sayed,, P. Neta, J.C. Mialocq, J.P. Fouassier ….


Education and positions :

Since 1993 : permanent research position (CNRS : National Center for Scientific Research) at  CEA Paris-Saclay, France

1997 6 months as visiting scientist in Pr. M. A. El-Sayed’s group, Atlanta, USA (CdS Qdots)
1993 Postdoctoral research, Dr Pedi Neta, N.I.S.T., Washington DC, USA (Radical Chemistry, Pulse Radiolysis)

Ph.D in Molecular-Physics and Chemistry, University of Paris-Sud, Orsay, France:
"Theoretical and experimental study of the relaxation of excited states of the DCM laser dye. Intra-molecular electron transfer and photo-isomerization. Solvent effects".

1988 Engineer in Chemistry Ecole Nationale Supérieure de Chimie de Mulhouse, France
1966 Born Besançon, France
