Science 266: 1018-1021 6.Development of single-molecule localization microscopy (SMLM) has sparked a revolution in biological imaging, allowing “super-resolution” fluorescence microscopy below the diffraction limit of light. The past decade has seen an explosion in not only optical hardware for SMLM but also the development or repurposing of fluorescent …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 ...

FRET is like a molecular ruler. It detects subtle, nano-scale changes in space. Combined with fast CCD and modern microscopic equipment, single molecule FRET (smFRET) is the perfect tool to probe both spacial and temporal domains of molecular interactions. Fluorescence Microscopy is an essential tool for modern biological experimentation.It is critical to investigate the catalytic activity of individual nanoparticles using in situ techniques. This review summarizes some of Prof. Xu’s recent accomplishments in studying the catalytic behavior of nanoparticles at the single-particle level using single-molecule fluorescence microscopy (SMFM).A new approach to quantitative single-molecule imaging by confocal laser scanning microscopy (CLSM) is presented. It relies on fluorescence intensity distribution to analyze the molecular occurrence statistics captured by digital imaging and enables direct determination of the number of fluorescent molecules and their diffusion rates without …
