Optofluidic Antenna Enhances Single-Molecule Sensitivity in Liquid
ERLANGEN, Germany, May 13, 2024 — Single-emitter fluorescence detection is used in diverse fields, from biophysics to quantum optics, to precisely observe processes at the single-molecule level. When performed under fluidic conditions, diffusion restricts the observation time and the detected photon counts, hampering the investigation of both slow and fast phenomena occurring in the molecule. To enhance the optical signal from emitters in a liquid and allow longer observation times, researchers at the Max Planck
