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…
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…
Purcell radiative rate enhancement of label-free proteins with ultraviolet aluminum plasmonics
Aleksandr Barulin, Prithu Roy, Jean-Benoît Claude +1
The vast majority of proteins are intrinsically fluorescent in the ultraviolet, thanks to the emission from their tryptophan and tyrosine amino-acid constituents. However, the prot…
Preventing Corrosion of Aluminum Metal with Nanometer-Thick Films of Al2O3 Capped with TiO2 for Ultraviolet Plasmonics
Prithu Roy, Clémence Badie, Jean-Benoît Claude +6
Extending plasmonics into the ultraviolet range imposes the use of aluminum to achieve the best optical performance. However, water corrosion is a major limiting issue for UV alumi…
Ultraviolet Photostability Improvement for Autofluorescence Correlation Spectroscopy on Label-Free Proteins
Aleksandr Barulin, Jérôme Wenger
The poor photostability and low brightness of protein autofluorescence have been major limitations preventing the detection of label-free proteins at the single molecule level. Ove…
Deep UV plasmonic enhancement of single protein autofluorescence in zero-mode waveguides
Aleksandr Barulin, Jean-Benoît Claude, Satyajit Patra +2
Single molecule detection provides detailed information about molecular structures and functions, but it generally requires the presence of a fluorescent marker which can interfere…
