Controlled manipulation of multiple cells using catalytic microbots

Key Points

• To evaluate whether catalytic microjet engines guided by external magnetic fields can selectively load, transport, and deliver multiple biological cells in fluid.
• Utilized self-propelled catalytic microjet engines capable of autonomous fluid propulsion.
• Applied external magnetic fields to remotely control trajectory, cell loading, transport, and targeted delivery.
• Catalytic microbots successfully captured, transported, and released multiple cells at designated fluid locations.
• External magnetic field application provided precise directional control over microbot navigation and cargo placement.
