Light-driven molecular shuttles modified on silicon nanowires

Immobilization of light-driven molecular shuttles onto the surface of the silicon nanowires (SiNWs) was realized. The alpha-cyclodextrins as the shuttles could be reversibly translocated along the thread by the optical stimuli. Such SiNWs-based molecular shuttles also exhibited sequential logic with optical stimuli as the input and fluorescence as the output.
