仿生螺旋结构微马达研究进展

Progress in the Bioinspired Helical-Micromotors

微型马达是对传统马达系统的功能拓展和有益补充,在污水处理、环境监测修复、靶向手术和药物输送等方面具有潜在应用前景。在流体环境中,高效率驱动性能是微型马达面临的重要挑战。依据理论和研究实践,人们普遍选择仿生螺旋结构作为马达的微驱动策略,并取得诸多新进展。本文从螺旋结构驱动的理论研究、螺旋微结构制备方法、螺旋马达的驱动机制和应用基础研究等几个方面综述了该领域近年的研究进展。最后提出了当前研究中亟待解决的科学问题并展望了未来重点研究方向。

Helical structure is ubiquitous in the living organism.Its functions originated from the interaction between these structures and the environment to ensure living organism to survive,such as,micro-driven,chiral locomotion,self-adaption and self-protection,which produced by billions of years of natural selection.Mechanism of the helical structure coupling with chemical reaction to interact with environments is a challenging task,which becomes a highly interdisciplinary of chemistry,physics,Materials and biology,moreover,has broad prospects in the areas of wastewater treatment,environmental monitoring,targeted surgery,drug delivery,and so on.In this review,to achieve a wide vision of recent progress on helical micromotors,some aspects are discussed,including the driving theory,preparation of micro-helical structures,specific mechanism of helical-robot moves and diverse applications of helical-robots.Finally,the unresolved questions of helical micromotors are given and the direction of further study are discussed.
