Liquid Bandages: Liquid Bandage Harvests Robust Adhesive, Hemostatic, and Antibacterial Performances as a First‐Aid Tissue Adhesive (Adv. Funct. Mater. 39/2020)

In article number 2001820, Feng Xu and co‐workers report a multifunctional hydrogel‐based liquid bandage (LBA) for trauma emergency; the resulting photo‐responsive chitosan‐based hydrogel harvests robust adhesive, hemostatic, and antibacterial performances as a first‐aid tissue adhesive. LBA is simply prepared without any extraneous photo‐initiator and toxic crosslinking agent for its safe use. Moreover, the utilization of this LBA can boost wound healing.
