光学操纵技术在许多领域都具有重要意义。例如，它们能够自下而上组装纳米材料，并对生物细胞和分子进行高分辨率和原位分析，为发现新材料、医学诊断和纳米医学提供机会。传统的光镊由于需要严格的光学条件和较高的光功率而限制了其应用。已经建立了低功率光学操纵技术的新策略。光热操纵，利用光子-声子转换和光控制的温度梯度下的物质迁移，是这样的新兴技术之一。阐明光-热-物质相互作用的基本物理和合理的光学环境工程是实现各种光热操纵功能所必需的。介绍了一系列新型光热操控技术的工作原理、设计思想和应用，包括气泡笔光刻、光热泳镊、光热镊、光热组装和光热印刷等。在气泡笔光刻中，等离子体基片的光学加热在固液界面处产生微气泡，以在基片上印刷各种胶体颗粒。还实现了半导体量子点在不同基底上的可编程气泡印刷和印刷的触觉控制。光热镊子的关键是能够将胶体颗粒从温度梯度的冷区域输送到热区域，或者负Soret效应。我们探讨不同的驱动力的两种类型的光热镊子。光-热泳镊子依赖于由胶体颗粒和活细胞的双电层中的结构化溶剂分子响应于热诱导熵而建立的异常介电常数梯度，并且光-热电镊子利用热泳诱导的热电场用于最小直径约20 nm的小纳米颗粒的低功率操纵。此外，通过将耗尽吸引力作为粒子-粒子或粒子-基底结合力引入光热镊子系统，我们实现了人工胶体物质的自底向上组装和可重构光学打印。除了液体环境中的光热操纵技术，我们还综述了基于电泳的气相光热操纵的最新进展。通过光学工程实现了光吸收材料的光泳捕获和传输，以调节光加热过程中的粒子-分子相互作用，并展示了一种新型的光阱显示器。对胶体对温度梯度响应的进一步理解必将促进光热操纵的进一步创新。光热操纵技术具有操作功耗低、光学结构简单、功能多样等优点，在生命科学、胶体科学、材料科学、纳米科学以及胶体功能器件和纳米医学等领域有着广泛的应用前景。
Optical manipulation techniques are important in many fields. For instance, they enable bottom-up assembly of nanomaterials and high-resolution and in-situ analysis of biological cells and molecules, providing opportunities for discovery of new materials, medical diagnostics, and nanomedicines. Traditional optical tweezers have their applications limited due to the use of rigorous optics and high optical power. New strategies have been established for low-power optical manipulation techniques. Optothermal manipulation, which exploits photon-phonon conversion and matter migration under a light-controlled temperature gradient, is one of such emerging techniques. Elucidation of the underlying physics of opto-thermo-matter interaction and rational engineering of optical environments are required to realize diverse optothermal manipulation functionalities. This account covers the working principles, design concepts and applications of a series of newly-developed optothermal manipulation techniques, including bubble-pen lithography, opto-thermophoretic tweezers, opto-thermoelectric tweezers, optothermal assembly, and opto-thermoelectric printing. In bubble-pen lithography, optical heating of a plasmonic substrate generates microbubbles at the solid-liquid interfaces to print diverse colloidal particles on the substrates. Programmable bubble printing of semiconductor quantum dots on different substrates and haptic control of printing have also been achieved. The key to optothermal tweezers is the ability to deliver colloidal particles from cold to hot regions of a temperature gradient, or a negative Soret effect. We explore different driving forces for the two types of optothermal tweezers. Opto-thermophoretic tweezers rely on an abnormal permittivity gradient built by structured solvent molecules in the electric double layer of colloidal particles and living cells in response to heat-induced entropy, and opto-thermoelectric tweezers exploit a thermophoresis-induced thermoelectric field for the low-power manipulation of small nanoparticles with minimum diameter around 20 nm. Furthermore, by incorporating depletion attraction into the optothermal tweezers system as particle-particle or particle-substrate binding force, we have achieved bottom-up assembly and reconfigurable optical printing of artificial colloidal matter. Beyond optothermal manipulation techniques in liquid environments, we also review recent progresses of gas-phase optothermal manipulation based on photophoresis. Photophoretic trapping and transport of light-absorbing materials have been achieved through optical engineering to tune particle-molecule interactions during optical heating, and a novel optical trap display has been demonstrated. An improved understanding of the colloidal response to temperature gradients will surely facilitate further innovations in optothermal manipulation. With their low-power operation, simple optics, and diverse functionalities, optothermal manipulation techniques will find a wide range of applications in life sciences, colloidal science, materials science and nanoscience, as well as in the developments of colloidal functional devices and nanomedicine.
