A Nature-Inspired Versatile Bio-Adhesive

Investigators presented a spatial multi-level physical-chemical and bio-inspired in situ bonding strategy is proposed, to develop a multifunctional hydrogel bio-glue using polyglutamic acid, tyramine hydrochloride, and tannic acid as precursors and DMTMM as condensation agent, which is used for tissue adhesion, hemostasis and repair.
