WebApr 12, 2024 · This paper describes a single-shot fluorescence lifetime imaging (FLIM) method. We use an optical cavity to create temporally delayed and spatially sheared … WebAbstract. We describe labeling of bacteria with amino-specific or sulfhydryl-specific Alexa Fluor dyes, methods that allow visualization of flagellar filaments, even in swimming cells. Bacterial flagellar filaments are long (~10 μm), but of small diameter (~20 nm), and their rotation rates are high (>100 Hz), so visualization is difficult.

WebFluorescent proteins and developments in superresolution (nanoscopy) and single-molecule techniques bring high sensitivity, speed, and one order of magnitude gain in spatial resolution to live-cell imaging. These technologies have only recently been applied to prokaryotic cell biology, revealing the exquisite subcellular organization of bacterial cells. … WebJul 1, 2024 · The presence of red or cyan fluorescent signatures from bacteria correlated with an average increase in wound area of 6.5% per week, indicating stalled or delayed wound healing. Fluorescence imaging information assisted in determining the location and extent of wound debridement, and the selection of dressings and/or antimicrobials. how does guy fawkes link to macbeth
