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 replicas of the fluorescent decay signal onto a time-gated intensified charged-coupled device (iCCD). This modality allows different portions of the decay signal to be sampled in … 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.
