摘　　要：具备光致异构性及乏氧响应性的偶氮苯为构建DNA纳米机器提供了动态响应元件.然而,受限于偶氮苯类化合物有限的光异构化反应,偶氮苯类DNA纳米机器的构建与应用仍然面临着巨大的挑战.本文梳理了基于偶氮苯的DNA纳米机器的构建方式及相应优缺点,总结了可见光响应的偶氮苯类DNA纳米机器的设计规则,并进一步综合评述了偶氮苯类DNA纳米机器在调控酶活性、物质运输和机械运动等方面的应用.本文有望推动开发更灵活的偶氮苯与DNA的偶联方式,并为偶氮苯类DNA纳米机器在生物医学上的应用带来一定启示.Azobenzene-integrated DNA nanomachines have inherited the photo-isomerized and hypoxia-responsive properties of azobenzene,thus enriching methodological toolboxes for designing dynamically responsive nanodevices.However,fabrication of azobenzene-based DNA nanomachine remains challenging due to the limitation of the response mechanism of azobenzene derivatives.This review elaborated the construction methods and corresponding advantages and drawbacks of azobenzene-integrated DNA nanomachine,and summarized the design rules of azoben⁃zene-based DNA nanomachine with visible light-responsive behaviors.Further,the applications of azobenzene-based DNA nanomachine in regulating the activity of biological enzyme,material transport,mechanical motion were reviewed.We expect that this review can facilitate the development of more flexible coupling methods between azo⁃benzene and DNA,and bring inspiration for the biomedicine application of azobenzene-integrated DNA nanomachine.
