The photocrosslinkable tissue adhesive based on copolymeric dextran/HEMA

► Photocrosslinkable gels were prepared from copolymeric urethane dextran and HEMA. ► The process of gelation was fast and simple with the help of photocuring. ► The addition of HEMA remarkably improved the adhesive strength and cell attachment. ► These gels were adequate to be novel tissue adhesives.
