Biofilm light microscopy
WebJul 1, 2024 · 2. Qualitative confocal microscopy imaging of matrix components. The functionality of bacterial biofilms is entwined with its microscale structure, as mass transport by diffusion and convection affects chemical gradients that dictate the limits of metabolic activity and the conditions in the microenvironment experienced by individual cells. 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 …
