Chargée de recherche CNRS - Equipe FunSurf

Activités / CV

Valérie Stambouli received her PhD in 1991 in Paris-Sud Orsay University (France). Then she moved to E.P.F.L. (Switzeland) where she was involved in physical and chemical characterizations to study the oxidization and tribological behavior of Fe based alloys. Since 1994, she is a full-time researcher of the Centre National de la Recherche Scientifique (CNRS). She has been working on the elaboration of metallic and dielectric films using P.V.D. techniques for microelectronics and Microsystems in Orsay University.

In 2002, she joined the LMGP in Grenoble where she initiated an interdisciplinary research program. She focuses on the elaboration and functionnalisation of nanostructured semiconductive materials for label-free biosensing.

Main research topics

  • Elaboration of metal oxide films using different techniques : PVD, MOCVD related techniques, electrodeposition process
  • Functionnalisation of nanostructured semiconductive materials (SnO2, Si, SiC) for biosensors applications.
  • Label free detection of DNA or bacteria on semiconductive materials using different techniques: I (V), electrochemical impedance spectrometry (EIS), optical detection by surface enhanced Raman spectrometry (SERS).
