モータータンパク質による人工筋肉で駆動するマイクロロボットの開発

抄録

In living cells, motor proteins and cytoskeletons are ubiquitous, and involved in various cellular functions. The functions are performed through distinct self-organized subcellular structures, such as contractile rings and stress fibers. Inspired by this, we intended to develop a molecular system consisting of microtubules and kinesins which can self-organize into various morphologies. By using a genetically engineered kinesin, we found that microtubules and the kinesins were self-organized into contractile fibers. In this presentation, we will discuss the mechanism of formation of the contractile fiber, and their possible applications as a novel actuator for microdevices.
