Nanotransducer‐impregnated self‐organized helical superstructures are found to exhibit unprecedented reversible handedness inversion upon irradiation by the dual‐wavelength near‐infrared light. Upon near‐infrared laser irradiation at 808 nm, the helical twist sense changes from right‐handed to left‐handed through an achiral liquid‐crystal phase, whereas its reverse process occurs upon the near‐infrared laser irradiation at 980 nm.
