  • Fast interaction dynamics of G-quadruplex and RGG-rich peptides unveiled in zero-mode waveguides

    03 janvier 2022

    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...

  • Single-molecule Detection of Ultrafast Biomolecular Dynamics with Nanophotonics

    28 janvier 2022

    Proteins can feature ultrafast structural dynamics in the nanosecond timescale which are very challenging to measure using conventional techniques such as single-molecule Förster resonance energy transfer (smFRET). So far, the limited fluorescence brightness...

  • Effective summary: seeing the intrinsic emission from a single natural protein with ultraviolet optical antennas

    06 avril 2022

    One of the ultimate goals of molecular biology is to watch how single proteins work in their native state. The current mainstream approach of single molecule fluorescence relies on introducing external fluorescent markers which can lead to severe issues...
