The COGNET research group at the Institute of Optics in Bordeaux follows a double ambition:  ​understanding light/matter interactions in individual nanoscale objects & developing single-molecule imaging approaches for answering key biological questions, often implying molecular diffusion processes. Our group is constitutively rooted in the LP2N NanoBioMicroscopy team which aims at performing nanoscale investigations in & of the complex matter using advanced light microscopy. 
​
Our current projects focus on single-wall carbon nanotube optics, super-resolution microscopy, single particle tracking strategies, molecular diffusion processes, quantitative phase imaging, developments of optical nanoprobes for high-contrast imaging, and several applications of these approaches to biology, with a strong interest for cancer science and neuroscience

November 21, 2020: 
​Congratulations to Antony for his paper accepted in Journal of Applied Physics about length measurements of carbon nanotubes through the analysis of their diffusion behaviour... independent of viscosity. Paper highlighted  by the Editor!

November 5, 2020: 
​Synergy grant from the ERC awarded to Laurent together with Laurent Groc, Erwan Bezard and Valentin Nägerl, all of us from labs of the Univ. Bordeaux campus. This will be the start of an ambitious project using new approaches in high-resolution microscopy at the service of a new conceptual framework in brain cell communication.
Looking forward to 6 years of great science!
