Abstract

Visible light driven Cu₂O–Au micromotors exhibit rapid on/off switching and speed control. Electrochemical measurements confirm that the light-induced movement of the Cu₂O–Au micromotors involves a self-electrophoresis mechanism modulated by the photoconductivity of Cu₂O. This study extends the utilization of the electromagnetic spectrum for micro/nanomotors into the visible range.
