WebJul 1, 1986 · To determine biofilm thickness by light microscopy, knowledge of biofilm refractive indices is, therefore, required. Due to biofilm's high water content, it is reasonable to assume that its refractive index will be close to that of water ( - 1.33). Work is presently being conducted to determine index of refraction in biofilms. WebJul 15, 2024 · Qin et al. used light-sheet microscopy to track the fate of individual cells. In another study, Rooney et al. imaged channels in mature biofilms that transport nutrients to the inside of biofilms.
WebIn this study, we combined dual-view light-sheet microscopy (5, 20–23) with intracellular puncta labeling technology (24, 25) to explore individual and collective cell dynamics and developmental patterns in living wild-type (WT) Vibrio cholerae biofilms (Fig. 1, A and B, and movies S1 and S2).We found that biofilm cells had one of two cell fates: They either … WebBecause biofilms are thick, they cannot be observed very well using light microscopy; slicing a biofilm to create a thinner specimen might kill or disturb the microbial community. Confocal microscopy provides clearer …
