Pristine anatase TiO₂ micromotors exhibit blue-light-driven phototaxis upon trace H₂O₂ sensitization. Experimental and computational studies reveal surface peroxide complex-mediated charge transfer. These eco-friendly micromotors demonstrate programmable swarming and cell manipulation via light-controlled diffusiophoresis.
