摘要：Biocompatible designed micromotor has attracted more and more concerns in the field of biomedicine due to their self-propulsion and delivery *** micromotors,mostly consisting of alkali earth metals,hydrogels,or other motile biomaterials,can effectively transform chemical energy into mechanical or kinetic energy to achieve the expected delivery of cargos to the sites of *** for conveying power,the modifiable surface and inner cavity of micromotors guarantee that their potential as versatile delivery systems for therapeutic ***,this review generalizes the propelling mechanisms,composites,and shapes of ***,the application of micromotor-derived composites for biomedicine delivery and other versatile purposes are also discussed.
