Dec 6, 2018 · Single-molecule imaging and tracking was performed on a custom-built total internal reflection fluorescence microscope equipped with an electron-multiplying CCD camera . To image cytoplasmic proteins within ~1 µ m thick E. coli cells, laser excitation was adjusted to highly inclined illumination mode [ 35 ]. The past decade has witnessed an explosion in the use of super-resolution fluorescence microscopy methods in biology and other fields. Single-molecule localization microscopy (SMLM) is one of the most widespread of these methods and owes its success in large part to the ability to control the on-off state of fluorophores through various chemical, photochemical, or binding-unbinding mechanisms.Stochastic approaches rely on creating transient spatial separation between fluorescent emitters, which enables the precise localization of single fluorophore molecules and are collectively termed single-molecule localization microscopy (SMLM). 15 SMLM requires switchable fluorophores, which can be activated stochastically. In most cases ...
Single-molecule fluorescence microscopy was used to investigate the dynamics of perylene diimide (PDI) molecules in thin supported polystyrene (PS) films at temperatures up to 135 °C. Such high temperatures, so far unreached in single-molecule spectroscopy studies, were achieved using a custom-built setup which allows for restricting the ...Super resolution fluorescence microscopy using single-molecule localization.

For the single-molecule study of helicases, the most used force techniques are optical and magnetic traps (reviewed in detail by Miller et al., 2018). The methods detailed here include single-molecule Förster (Fluorescence) resonance energy transfer (smFRET), protein-induced fluorescence enhancement (smPIFE), and nucleation experiments (Fig. 1).
