The present invention relates to a biocompatible polymeric hydrogel patch which is modified with a catechol group or pyrogallol group and has excellent biocompatibility and tissue adhesion, and use thereof for drug delivery, cell transplantation, and tissue regeneration. The biocompatible polymeric hydrogel patch modified with a catechol group or a pyrogallol group has remarkably excellent mechanical properties and tissue adhesion, as compared to solution-based bulk hydrogels, and thus can carry cells and a drug in vivo for a long period of time and safely and efficiently deliver same to a target site. |
