T. Si, Q. He, and co‐workers demonstrate the fuel‐free, highly efficient propulsion of gold nanoshell‐functionalized polymeric multilayer rockets under NIR illumination. On page 577, the NIR‐driven rockets, fabricated by nanoporous template‐assisted polyelectrolyte layer‐by‐layer assembly, can move at a speed of 160 μm s −1 owing to the self‐thermophoretic forces generated by the photothermal effect. This NIR‐driven rocket is able to target cancer cells without side effects on the cell under exposure to NIR, indicating considerable promise for future biomedical applications.
