Enzyme location-dependent motion behavior. (a) Schematic illustration of SNT-urease with enzyme all over (SNT-urease-A), inside (SNT-urease-I), and outside (SNT-urease-O) the nanotube, and corresponding SEM images. (b) Longitudinal average velocity of the three nanotubular motors with average length of 20 μm. (c) Rotational diffusion of the three nanotubular motors with average length of 5.5 μm. Error bars indicate standard error of the mean, N = 10.
