Light fuel : Photoresponsive nanoscale tweezers fuelled by photons were constructed with azobenzene‐modified DNA. The tweezers were photoswitched to the open state with UV light irradiation ( λ =330–350 nm) and to the closed state with visible light ( λ =440–460 nm) without the addition of further oligonucleotides as fuel.
