以纳米级分辨率访问和控制物体的光子方法非常重要，因为它们具有高灵敏度、远程性和各种实施工具等吸引人的特性。我们报告了使用光异构化分子实现的自给式光子控制 DNA 镊子。这种组合可以有效地利用传播光以纳米级分辨率控制物体，这使我们能够捕捉闪烁的多个物体的信号并一次在一个区域上控制它们。实验结果表明，自给式光子控制DNA镊子通过光照射交替打开和关闭状态，在重复操作过程中操作效率几乎一致。 (C) 2009 日本应用物理学会
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.
