Figure 5

Analysis of 3D motion of urease micromotors in ionic media after 5 minutes of adding urea and/or NaCl. (a) 3D trajectories of three urease micromotors and (b) MSDs from the , , and dimensions of urease micromotors in water. (c) 3D trajectories of three urease micromotors and (d) MSDs from the , , and dimensions of urease micromotors in water with 200 mM urea. (e) 3D trajectories of three urease micromotors and (f) MSDs from the , , and dimensions of urease micromotors in 1 mM NaCl with 200 mM urea. Insets: 2D and 3D MSDs of urease micromotors in (b) water, (d) water with 200 mM urea, and (f) 1 mM NaCl with 200 mM urea.
