To achieve these fantastic applications, effective control of the micro\/nanomotor is essential. Light has been proved as the most versatile method for microswimmer manipulation, while the light propagation direction, intensity, and wavelength have been explored as controlling signals for light\u2010responsive nanomotors. Here, the controlling method is expanded to the polarization state of the light, and a nanomotor with a significant dichroic ratio is demonstrated. Due to the anisotropic crystal structure, light polarized parallel to the Sb\n                    <jats:sub>2<\/jats:sub>\n                    Se\n                    <jats:sub>3<\/jats:sub>\n                    nanowires is preferentially absorbed.

Furthermore, by incorporating two cross\u2010aligned dichroic nanomotors, a polarotactic artificial microswimmer is achieved, which can be navigated by controlling the polarization direction of the incident light. Compared to the well\u2010studied light\u2010driven rotary motors based on optical tweezers, this dichroic microswimmer offers eight orders of magnitude light\u2010intensity reduction, which may enable large\u2010scale nanomanipulation as well as other heat\u2010sensitive applications.\n
