Aug 26, 2021 · Single-molecule techniques can be broadly split into two classes: those based on applications and measurements of force and those based on detection of fluorescence. 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). S. Farooq. M. Yusuf. Chromosome Research (2021) Recent advances in fluorescence super-resolution microscopy are providing important insights into details of cellular structures. To acquire three ...(a) Single molecule fluorescence microscopy of defect-mediated EnT. A 6 mW 355 nm laser excites ZnO NC donors, and a 6 mW 532 nm laser excites A555 acceptors immobilized on a quartz slide.
