Photoresponsive DNA nanomaterials represent a new class of remarkable functional materials. By adjusting the irradiation wavelength, light intensity, and exposure time, various photocontrolled DNA-based systems can be reversibly or irreversibly regulated in respect of their size, shape, conformation, movement, and dissociation/association. This Review introduces the most updated progress in the development of photoresponsive DNA-based system and emphasizes their advantages over other stimuli-responsive systems. Their design and mechanisms to trigger the photoresponses are shown and discussed. The potential application of these photon-responsive DNA nanomaterials in biology, biomedicine, materials science, nanophotonic and nanoelectronic are also covered and described. The challenges faced and further directions of the development of photocontrolled DNA-based systems are also highlighted.
