Recent research progress on DNA walker-based molecular machines

Abstract

As an important step in learning from nature, artificial molecular machines have attracted more and more public attention. Due to the distinct advantages of well-defined Watson-Crick base pairing rule, programmable sequence, diverse and controllable secondary structures, DNA are considered as promising building blocks for artificial molecular machines. In this review, recent research progress on DNA walker, an important member in artificial molecular machine family, is introduced on the basis of difference in driving forces, and the future development of this kind of molecular machines is prospected.
