A micro/nanomotor is a micro- or nanoscale device that converts energy into movement and force. Micro/nanomotors represent a fundamental step toward the realization of practical nanomachines. Inspired by the biomachines of nature, humans have devoted considerable effort to the development of artificial micro/nanoscale machines analogous to the macroscopic ones in our lives.
The biomachines created by nature through millions of years of evolution are able to perform complicated tasks precisely, forming the foundations of biological systems. In fact, machines are not limited to human design. Throughout history, humans have developed many machines to help change the world. A machine is a tool that can perform intended tasks using energy. The use of tools can be traced back to the beginning of recorded history and represents a significant step in the evolution of mankind.
