Overview of different fluorescent probes developed to detect single DNA molecules using single-molecule fluorescence microscopy. (From left to right) DNA binding dyes such as YOYO-1 and SYTOX Orange (SxO) remain largely non-fluorescent in solution and become highly fluorescent upon interaction with the bases in DNA, enabling direct visualisation during complex biochemical reactions.A recent addition to the toolbox of super-resolution microscopy methods is fluorescence-lifetime single-molecule localization microscopy (FL-SMLM). The synergy of SMLM and fluorescence-lifetime imaging microscopy (FLIM) combines superior image resolution with lifetime information and can be realized using two complementary experimental approaches: confocal-laser scanning microscopy (CLSM) or ...Today, fluorescence microscopy is an indispensable tool in single-molecule investigations, providing a high signal-to-noise ratio for visualization while still retaining the key features in the physiological context of native biological systems.

For all these kinds of experiments there exists a subset of fluorescence microscopy techniques termed single molecule fluorescence microscopy (SMFM). SMFM allows for the investigation of the behavior of single molecules (or small groups) under very strict conditions, which ensures that each molecule is in the same state as any other molecule. Single-molecule fluorescence-microscopy techniques can provide mechanistic detail about molecular interactions such as enzymatic turnover rates, dissociation and association rates, and stoichiometries of interacting species [16], [17], [18]. As such, they are considered ‘bottom-up’ methods in that by visualising and analysing information ...See full list on photometrics.com
