摘要
胶体马达是将化学能、光能、声能或其它形式的能量转化为机械运动并能够完成复杂任务的微纳米系统。"自下而上"可控组装技术与"自上而下"技术的有效结合赋予了所制备的自驱动胶体马达良好的功能特性,如便于大规模制备,具有良好的刺激响应性以及便于实现多种构筑基元的集成等。作为一种重要的可控组装方法,层层组装可以实现对组装体组成、结构和功能的有效控制。2012年,我们率先利用层层组装技术制备了气泡驱动的阴阳型聚电解质多层微胶囊马达。最近,我们在基于可控组装结构胶体马达的制备、运动控制及应用等方面开展了系列工作,实现了阴阳微胶囊型、管状及盘状胶体马达的可控制备,近红外激光辐照下的马达运动开关控制以及马达在靶向药物递送、光热治疗以及水中污染物清除等方面的应用。
Colloid motors, which are tiny devices capable of performing self-propelled motion in fluids through converting different types of energies into mechanical movement. Combined with the top-down approaches, controlled assembly affords the colloid motors with the advantages of: i) mass production, ii) response to the external stimuli, and iii) access to multifunctionality.[1,2] As an important branch of controlled assembly, layer-by-layer assembly(Lb L) is a versatile tool that can realize the effective control over the structures, compositions, and functionalities of the resulting assembled architectures. We first employed the Lb L technology for the controlled fabrication of colloid motors with the structure of the hollow capsule.[3,4] This presentation will summarize our recent progress on the controlled fabrication, motion control, and applications of colloid motors(e.g., targeted drug delivery, photothermal therapy and environmental remediation) based on controlled Lb L assembly.
