Abstract:

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 azobenzene-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 azobenzene and DNA, and bring inspiration for the biomedicine application of azobenzene-integrated DNA nanomachine.

Key words: Azobenzene, DNA nanomachine, Photoisomerization, Hypoxia-responsive, Visible light-responsive
