原文详细摘要如下：Switchable chemotaxis is vital for motile microorganisms to seek benefits or avoid harms. Inspired by nature, we herein, for the first time, demonstrate an artificial enzyme-powered micromotor which can autonomously regulate the propulsion mechanism as well as motion directionality by sensing solely the change of fuel concentration (Cf) in its surroundings. The as-designed micromotors have a pot-like microstructure with ureases immobilized on the inner surface. With the confined effect of the pot-like microstructure and unique features of urease catalytic reaction that molecular products are further reacted into ions, their propulsion mechanism can be reversibly adjusted between ionic diffusiophoresis and microbubble recoils when Cf changes. Consequently, the as-developed micromotors under magnetic field are able to self-turn back if local Cf differs greatly in their surroundings, indicating the achievement of achieve positive and negative chemotaxis by sensing local Cf. Meanwhile, the micromotors also show highly enhanced migration speed by microbubble-ejection, up to 60 μm/s, around 30 body lengths per second at physiological urea concentrations. The peculiar design strategy based on pot-like microstructures further enables the mesoporous silica outer surface to be easily functionalized for applications such as stimuli-responsive delivery-associated therapies besides for “smart” artificial micro/nanomotors (MNMs), and thus promote their in vivo biomedical applications.
