(A) Optical micrograph of the microchamber. Yellow arrows point to an isolated E. coli in the microchamber. The bar indicates a length of 20 μm. (B) The magnified micrographs show sensor-protein dynamics of isolated single E. coli at times of (a) 0 min, (b) 180 min, (c) 225 min, (d) 315 min, and (e) 435 min after the inoculation.
