Single-molecule imaging represents a subset of fluorescence microscopy techniques that uses fluorescent tags to detect and analyze individual single molecules. This allows the activity of single molecules to be visualized with high signal-to-noise without disturbing the physiological conditions of the biological system.

Single-molecule fluorescence (or Förster) resonance energy transfer (or smFRET) is a biophysical technique used to measure distances at the 1-10 nanometer scale in single molecules, typically biomolecules. It is an application of FRET wherein a pair of donor and acceptor fluorophores are excited and detected at a single molecule level.In a typical SMFD, the interested target signal can be translated to the fluorescent signal via direct/indirect fluorophore labelling, and the signal of every individual fluorophore can be imaged by single-molecule fluorescent microscopy (e.g., total internal reflection fluorescence (TIRF) [54] and confocal microscopy [55]) and subsequently ...Feb 11, 2021 · Single-molecule fluorescence microscopy (SMFM) has been considered as a powerful tool to study nanocatalysis of single nanoparticles, due to its single-molecule sensitivity and high spatiotemporal resolution. In this review, we discuss recent progresses on investigating nanocatalysis at single-molecule/particle level by using SMFM. ….
