Artificial molecular machines:precision and visualization of nanoscale dynamic processes
Molecular machines play a pivotal role in the natural world,executing a myriad of intricate functions in biological processes to regulate dynamic behaviors across various scales.Inspired by biological systems,scientists are devoted to investigating the precise construction and directed motion of artificial molecular machines at the nanoscale.Through hierarchical assembly,these endeavors aim to achieve signal transduction and functional amplification,thereby propelling the design and development of dynamic intelligent materials.However,the accurate construction of complex artificial molecular machines using novel methods,the"visualization"of the motional dynamics at the molecular scale,and the establishment of connections with other molecular-level substructures and the external environment through the utilization of molecular-level movements to engineer artificial structures have remained focal points in the field of molecular machines.Based on the work conducted by our research group,this review systematically delineates the precise structural construction at the nanoscale,signal output,and research pertaining to the transmembrane transport of artificial molecular machines.In the conclusion part,the challenges in the field are summarized,particularly in the realm of multiscale refinement and functionalization,and prospects for the development of molecular machines in the macroscopic intelligent materials domain are discussed.
