Abstract

Various types of nanocomponents have been developed to construct a nanodevice or nanomachine. Here, we add a new nanocomponent that has the function of self-oscillation. A thermoresponsive polymer carrying a Ru complex, a catalyst of the Belousov-Zhabotinsky reaction, was synthesized and immobilized on a glass plate. Periodic turbidity changes in the aqueous solution of the polymer were observed, and nanoscale self-oscillation of the immobilized polymer was observed by a scanning probe microscope.

摘要

人们已经开发出各种类型的纳米组件来构建纳米器件或纳米机器。在此，我们添加了一种具有自振荡功能的新型纳米组件。合成了一种负载钌配合物（别洛索夫-扎博京斯基反应的催化剂）的热响应聚合物，并将其固定在玻璃板上。观察到聚合物水溶液中的周期性浊度变化，并通过扫描探针显微镜观察到固定化聚合物的纳米级自振荡。
