Fast interaction dynamics of G-quadruplex and RGG-rich peptides unveiled in zero-mode waveguides
G-quadruplex structures of DNA are promising target sites for anticancer therapy. However, the interaction of G-quadruplex with proteins remains poorly understood, notably the association and dissociation kinetics. In a recent Nucleic Acid Research publication...

Ultraviolet Nanophotonics Enables Autofluorescence Correlation Spectroscopy on Label-Free Proteins With a Single Tryptophan
Proteins are naturally fluorescent in the ultraviolet, offering an appealing approach to probe proteins in their native state without introducing any external fluorescent label. The UV autofluorescence of proteins is based on the presence of tryptophan...

High-Throughput Fabrication of Zero-Mode Waveguide Nanoapertures for Enhanced Single-Molecule Fluorescence Detection
Our recent publication in Small presents a new scalable way to fabricate zero-mode waveguides (ZMWs) which are metallic nanoapertures confining light into volumes 1000x smaller than the diffraction limit. These nanostructures enable single-molecule fluorescence...

Review Nanoholes
Drilling holes of nanometric dimensions in a metal film is a way conceptually simple to realize new nanophotonic components. In spite of its visible simplicity, a hole drilled in an opaque screen still inspires new perspectives of applications. In a review...

Any future for the CNRS ?
So it didn’t take long to the newly elected French government to threaten (again) the CNRS. Now, the transfer of CNRS researchers to universities appears intended, giving a large power to universities deans, and totally weaking the CNRS institution. This...
