| Abstract: | Hydrogels,three-dimensional networks of hydrophilic polymers that are able to swell large amounts of water,can be made to resemble the physical characteristics of soft tissues.Photocrosslinkable hydrogels are being investigated for a number of medical applications because of fast curing rates,spatial and temporal control and minimal heat production.This review presents advantages of photocrosslinkable hydrogels and summarizes their applications in drug delivery system,tissue engineering scaffold,cell controlled release,cell encapsulation and injectable hydrogels.All these studies indicate that photocrosslinkable hydrogels could be better employed in the tissue engineering and regeneration medical field. |
