Full Spectrum Tunable Visible‐Light‐Driven Alloy Nanomotor

Abstract

Micro/nanomotors (MNMs) are emerging machinery by virtue of their tempting applications in noninvasive microsurgery, environmental remediation, and advanced nanomanufacturing. Notably, the light‐powered MNMs generate propulsion thrust by absorbing photons and potentially respond differently to different energy photons, which enable their feasibility of remote signaling, independent addressing, and multi‐channel controllability. In this study, an inorganic nanomotor based on solution‐processed cation exchanged core–shell alloy nanowire is demonstrated with continuous tunability in the visible spectrum. The spectrum response of nanomotor can be selectively tailored through nanomotor composition, which provides a simple platform for future multi‐channel navigated MNMs system and moves a step toward massive production of MNMs with advanced functionalities.
