摘要
In the past few years,photo-crosslinkable hydrogels have drawn a great attention in tissue engineering applications due to their high biocompatibility and extracellular matrix(ECM)-like structure.They can be easily biofabricated through exposure of a photosensitive system composed of photo-crosslinkable hydrogels,photo-initiators and other compounds such as cells and therapeutic molecules,to ultraviolet or visible light.With the development ofbiofabrication methods,many researchers studied the biological applications of photo-crosslinkable hydrogels in tissue engineering,such as vascular,wound dressing and bone engineering.This review highlights the biomaterials for photo-crosslinkable hydrogels,biofabrication techniques and their biological applications in tissue engineering.Meanwhile,the challenges and prospects of photo-crosslinkable hydrogels are discussed as well.
