COGNET RESEARCH - NanoBiophotonics
Laurent COGNET, Research Director & Principal Investigator at CNRS
​Institute of optics - University of Bordeaux, France



​Our interdisciplinary research in nano-biophotonics is motivated by a double aim: understanding light/matter interactions in individual nanoscale objects & developing single-molecule imaging approaches for answering key biological questions.
​
Our current projects focus on single-wall carbon nanotube optics, super-resolution microscopy, single particle tracking strategies, quantitative phase imaging, developments of optical nanoprobes for high-contrast imaging, and several applications of these approaches to biology, with a strong interest to neuroscience where nanoscale imaging provides unprecedented tools to study the complex architecture of the brain.

  • Single-Molecule/particle Tracking
  • Super-resolution Localization Microscopy
  • Imaging & Exciton Spectroscopy of individual single wall carbon nanotubes.
  • Quantitative Phase Imaging
  • Photothermal Microscopy (metallic nanoparticles, semiconductor nanocristals, single-wall carbon nanotubes...)
  • Novel Single-Molecule Nanoprobes
  • Biophotonics - Neurophotonics
