Micromotors (MMs) are micro and nanoscale devices capable of converting energy into autonomous motion. Metal-organic frameworks (MOFs) are crystalline materials that display exceptional properties such as high porosity, internal surface areas, and high biocompatibility. As such, MOFs have been used as active materials or building blocks for MMs. In this highlight, we describe the evolution of MOF-based MMs, focusing on the last 3 years. First, we covered the main propulsion mechanisms and designs, from catalytic to fuel-free MOF-based MMs. Secondly, we discuss recent applications of new fuel-free MOFs MM to give a critical overview of the current challenges of this blooming research field. The advantages and challenges discussed provide a useful guide for the design of the next generation MOF MMs toward real-world applications.
微电机（MMs）是能够将能量转化为自主运动的微米和纳米级装置。金属有机框架（MOFs）是具有高孔隙率、内表面积和高生物相容性等优异特性的晶体材料。因此，MOFs已被用作MMs的活性材料或构建单元。在本综述中，我们描述了基于MOF的MMs的发展历程，重点关注过去三年。首先，我们介绍了主要的推进机制和设计，从基于催化的MOF微电机到无燃料的MOF微电机。其次，我们讨论了新型无燃料MOF微电机的最新应用，以对这一蓬勃发展的研究领域当前面临的挑战进行批判性概述。所讨论的优点和挑战为下一代MOF微电机面向实际应用的设计提供了有用的指导。
