One-step DNA Detection through Dual-Color Confocal Analysis of DNA-Assembled Scattering Nanoparticles: Case of a Fragment of Sesame

Stephanie VIAL

Institut Fresnel, Aix Marseille Université

Stephanie Vial holds her PhD on materials science from the University of Clermont-Ferrand (France) in 2005. Her research interest focuses on the use of nanoparticles, especially gold nanorods, as a tool for biological applications such as diagnostic and drug delivery. She is expert in the synthesis of nanoparticles, their surface functionalization, their self-assembly; and, the characterization and control of their physical and biological properties. She is currently postdoc at Institut Fresnel (Marseille) working on the development a novel concept based on DNA and protein detection using dual-color photon cross correlation spectroscopy of metallic nanoparticles


DNA-based detection methods have many applications in clinical diagnosis, food science, and environmental control. However, most of the analytical techniques currently in use, such as PCR, are expensive, cumbersome, and time... [ view full abstract ]
