Abstract
Nucleic acids are widely used in biomedical applications because of their programmability and biocompatibility. The light responsive nucleic acids have attracted wide attention due to their remote control and high spatiotemporal resolution. In this review, we summarized the latest developments in biomedicine of light responsive molecules. The molecules which confer light responsive properties to nucleic acids were summarized. The binding sites of molecules to nucleic acids, the induced structural changes, and functional regulation of nucleic acids were reviewed. Then, the biomedical applications of light responsive nucleic acids were listed, such as drug delivery, biosensing, optogenetics, gene editing, etc. Finally, the challenges were discussed and possible future directions of light-responsive nucleic acids were proposed.
