Abstract
Photonic methodologies to access and control objects with a nano-scale resolution are important because of their attractive features including high sensitivity, remoteness, and various implementation tools. We report self-contained photonically-controlled DNA tweezers implemented using photoisomerizing molecules. This composition is effective to control objects with a nanoscale resolution using propagating light, which enables us to capture signals of multiple objects in a twinkle and control them over an area at a time. Experimental results demonstrated that the self-contained photonically-controlled DNA tweezers were alternated the open and closed states by light irradiation with almost uniform operation efficiency during repeated operations.
