Abstract

Field-controlled microrobots have attracted extensive research in the biological and medical fields due to the prominent characteristics including high flexibility, small size, strong controllability, remote manipulation, and minimal damage to living organisms. However, the fabrication of these field-controlled microrobots with complex and high-precision 2- or 3-dimensional structures remains challenging. The photopolymerization technology is often chosen to fabricate field-controlled microrobots due to its fast-printing velocity, high accuracy, and high surface quality. This review categorizes the photopolymerization technologies utilized in the fabrication of field-controlled microrobots into stereolithography, digital light processing, and 2-photon polymerization. Furthermore, the photopolymerized microrobots actuated by different field forces and their functions are introduced. Finally, we conclude the future development and potential applications of photopolymerization for the fabrication of field-controlled microrobots.

光聚合制备的场控微型机器人。

场控微型机器人以其灵活性高、体积小、可控性强、可远程操作、对生物体损伤小等突出特点，在生物和医学领域引起了广泛的研究。然而，这些具有复杂和高精度二维或三维结构的场控微型机器人的制造仍然具有挑战性。光聚合技术由于其打印速度快、精度高、表面质量好等优点，常被用于制造场控微型机器人。本文将用于制造场控微型机器人的光聚合技术分为立体光刻、数字光处理和双光子聚合。此外，还介绍了在不同电场力作用下的光聚合微机器人及其功能。最后，展望了光聚合技术在制备场控微型机器人中的应用前景。
