Photosensitive hydrogels are water swollen three-dimensional polymers, which are responsive to light. Photosensitive hydrogels have properties similar to natural extracellular matrix. They can be operated remotely without contact and spatiotemporally controlled with high precision by light stimulation. Accordingly, they are widely studied and applied in the fields of biological scaffold, drug delivery, three-dimensional cell culture and stomatology. This study reviews the applications of photosensitive hydrogels in biomedical fields based on domestic and foreign literature. Their potential for development and potential future challenges are also outlined.

Key words: photosensitive hydrogel, biological scaffold, drug delivery, cell encapsulation
