Abstract:
Two-photon-regulated, shape-changing DNA nanostructures are demonstrated by integrating a DNA nanotube with a two-photon photocleavable module that enables the opening of the cavities of tube, and becomes partially single-stranded in response to two-photon excitation under 800 nm fs laser pulses.
