A novel active agent-eluting hemostatic agent and methods of use and manufacture thereof are presented. A polymer, such as gelatin, is used as the base for a hemostatic agent. The gelatin is crosslinked with a chemical crosslinker, such as a carbodiimide, in the presence of an active agent. The active agent may be an anesthetic or antimicrobial, such as an antibiotic. The novel process allows for the active agent to be both covalently bound to the gelatin as well as be trapped within cages in the gelatin that are formed from the crosslinking. This dual measure allows for controlled and sustained release of the active agent from the hemostatic agent to reduce surgical site infections.

A dynamic antimicrobial hydrogel based on natural receptor-ligand recognition, and a preparation method and use thereof are provided. A ligand vancomycin and a receptor AA-based material each are first modified with a modification material, and then a photoinitiator is added to prepare a hydrogel material under irradiation of ultraviolet (UV) light. In the hydrogel, a three-dimensional (3D) network structure is formed through crosslinking. After undergoing a fracture under an external pressure, the hydrogel can rapidly heal itself through crosslinking due to a ligand-receptor interaction and a multi-hydrogen-bond interaction, which bio-mimicks a natural ligand-receptor interaction to realize the dynamics of the hydrogel material. The high antiomicrobial activity of vancomycin imparts the functionality of the hydrogel material; and the physiologically-derived monomer improves the biocompatibility and reduces the biological toxicity.
