Ionic Species Affect the Self-Propulsion of Urease-Powered Micromotors
Motion dynamics, enzymatic activity, and pH change produced by urease micromotors for different concentrations of phosphate-buffered saline (PBS) at 200 mM urea. (a) Representative trajectories (axis divided in 10 μm). (b) Average micromotor MSDs. (c) Average speed and enzymatic activity of micromotors. In (b, c), results are shown as the . (d) pH change produced by micromotors.
