Ionic Species Affect the Self-Propulsion of Urease-Powered Micromotors

Figure 4

Motion dynamics, enzymatic activity, and pH change produced by urease micromotors for different concentrations of NaCl at 200 mM urea. (a) Representative trajectories (axis divided in 5 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.
