Enzyme-powered micro- and nanomotors. (A) Bubble propulsion of (a) tubular microjet and (b) Janus mesoporous cluster motor modified with catalase. (B) Self-propulsion of Janus hollow mesoporous nanomotors powered by various enzymes, catalase, urease, and glucose oxidase (GOx). (C) Urease powered hollow capsule: (a) motion control by manipulating the enzymatic activity, (b) “on”/“off” motion control by addition of inhibitor and DTT, and (c) repeated motion control up to 8 cycles.
