Robust and Photocontrollable DNA Capsules Using Azobenzenes Fumiaki Tanaka, Toshio Mochizuki, Xingguo Liang, Hiroyuki Asanuma, Shukichi Tanaka, Various three-dimensional structures have been created on a nanometer scale using the self-assembly of DNA molecules. However, ordinary DNA structures breakdown readily because of their flexibility. In addition, it is difficult to control them by inputs from environments. Here, we construct robust and photocontrollable DNA capsules using azobenzenes. This provides a method to construct DNA structures that can survive higher temperatures and can be controlled with ultraviolet irradiation. Graphical abstract
