已经构建了一对DNA纳米环来模拟齿轮。纳米齿轮可以不断地相互移动。每个齿轮由一个DNA双链环和三个单链牙齿组成。两个齿轮上的齿由链接线连接在一起，链接线与齿轮齿互补。通过用链条移动机构移除链接线，使齿彼此分开。
A pair of DNA nanocircles has been constructed to model gears. The nanogears can move against each other continuously. Each gear consists of a DNA duplex circle and three single-stranded teeth. The teeth on the two gears are brought together by linker strands, which are complementary to the gear teeth. The teeth are separated from each other by removal of the linker strands with a strand displacement mechanism.
