活性胶体能够利用环境中的能量进行自主运动，其相关研究对于推进微纳米技术具有重要意义。光作为一种无处不在的可驱动胶体粒子运动的外部刺激，具有远程可控性、灵活可调性和高时空分辨率等独特的优点。在这里，光驱活性胶体被定义为在光照射下可以自主运动的微/纳米级颗粒。广义上讲，它们包括完全或部分由无机材料、微液滴及有机物质组成的微/纳米马达。光驱活性胶体的推进主要依赖于光引发的化学或物理转化，包括但不限于光化学反应、分子异构、压力或温度变化。在本章中，我们首先全面概述了与光化学反应、光电化学现象、光热效应、光异构化以及光动量转移相关的各类型光引发转化及其涉及到的驱动机理，并将它们与典型的光驱活性胶体系统模型联系起来。此外，我们总结了光驱活性胶体在运动调节、趋光性运动及光诱导集群方面的独特性，同时介绍了它们在仿生学、货物捕获和运输、环境修复和生物医学工程方面的重要进展。
原文摘要如下：Active colloids, capable of autonomous motion by harnessing energy available in their surroundings, are of significance for advancing micro/nanoscale technologies. Light, as a ubiquitous external stimulus to propel the motion of colloid particles, offers unique benefits such as remote controllability, flexible tunability, and high temporal and spatial resolution. Light-driven active colloids are defined as the particles at the micro/nanoscale that can swim under light irradiation. They, broadly speaking, include micro/nanomotors composed entirely or partially of inorganic materials, microdroplets and organic matters. Light-driven active colloids are propelled primarily relying on light-initiated transformations involving but not limited to photochemical reaction, molecule isomerism, and pressure and temperature changes. In this chapter, we provide a comprehensive overview of various types of light-initiated transformations associated with propulsion mechanisms related to photochemical reactions, photoelectrochemical phenomena, photothermal effect, and photoisomerisation, as well as optical momentum transfer. Then, we relate them to typical models of light-driven active colloidal systems. Furthermore, we summarise the uniqueness of their motion in terms of motion modulation, phototaxis, and light-induced swarming, while highlighting the important progress towards bionics, cargo capture and transport, environmental remediation, and biomedical engineering.
