Achieving High Temporal Resolution in Single-Molecule Fluorescence Techniques using Plasmonic Nanoantennas
Sunny Tiwari, Prithu Roy, Jean-Benoît Claude +1
Single-molecule fluorescence techniques are essential for investigating the molecular mechanisms in biological processes. However, achieving sub-millisecond temporal resolution to…
Germanium-based nearly hyperuniform nanoarchitectures by ion beam impact
Jean-Benoit Claude, Mohammed Bouabdellaoui, Jerome Wenger +3
We address the fabrication of nano-architectures by impacting thin layers of amorphous Ge deposited on SiO with a Ga ion beam and investigate the structural and optical…
Ultraviolet Nanophotonics Enables Autofluorescence Correlation Spectroscopy on Label-Free Proteins With a Single Tryptophan
Prithu Roy, Jean-Benoît Claude, Sunny Tiwari +2
Using the ultraviolet autofluorescence of tryptophan aminoacids offers fascinating perspectives to study single proteins without the drawbacks of fluorescence labelling. However, t…
Fluorescence Brightness, Photostability and Energy Transfer Enhancement of Immobilized Single Molecules in Zero-Mode Waveguides Nanoapertures
Satyajit Patra, Jean-Benoît Claude, Jérôme Wenger
Zero-mode waveguide (ZMW) nanoapertures are widely used to monitor single molecules beyond the range accessible to normal microscopes. However, several aspects of the ZMW influence…
Ultraviolet optical horn antennas for label-free detection of single proteins
Aleksandr Barulin, Prithu Roy, Jean-Benoît Claude +1
Single-molecule fluorescence techniques have revolutionized our ability to study proteins. However, the presence of a fluorescent label can alter the protein structure and/or modif…
Single Photon Source from a Nanoantenna-Trapped Single Quantum Dot
Quanbo Jiang, Prithu Roy, Jean-Benoît Claude +1
Single photon sources with high brightness and subnanosecond lifetimes are key components for quantum technologies. Optical nanoantennas can enhance the emission properties of sing…
