利用聚亚苯基亚乙烯基和聚苯胺的低聚物构建了一种DNA纳米结构的电光调制器。在DNA折纸中组装含有每种功能分子的分子装置。构建体形成“X”形，并通过原子力显微镜观察。响应于氧化还原重构，该装置可逆地改变荧光信号输出。这种分子自组装策略提供了制造难以通过共混实现的独特材料复合材料的机会。该战略提供了一种“即插即用”的形式，可能会导致许多新的功能。
An electro-optical modulator was constructed using a DNA nanostructure scaffold with oligomers of poly(phenylenevinylene) and polyaniline. A molecular device containing one each of the functional molecules was assembled in a DNA origami. The constructs formed an “X” shape and were visualized by atomic force microscopy. In response to redox reconfiguration, the device reversibly altered fluorescence signal output. This molecular self-assembly strategy provides opportunities to make unique material composites that are difficult to achieve by blending. The strategy offers a “plug and play” format that may lead to many new functions.
