[Abstract]  Bacterial surface adhesion, the first step in many important processes including biofilm formation and tissue invasion, is a fast process that occurs on a time scale of seconds. Adhesion patterns tend to be stochastic and spatially heterogeneous, especially when bacteria are present in low population densities and at early stages of adhesion to the surface. Thus, in order to observe this process, a high degree of temporal resolution is needed across a large surface area in a way that allows several replicates to be monitored. Some of the current methods used to measure bacterial adhesion include microscopy, staining-based microtiter assays, spectroscopy, and PCR. Each of these methods has advantages in assaying aspects of bacterial surface adhesion, but none can capture all features of ...
