Abstract
Disclosed herein are antimicrobial materials comprising a carbohydrate-templated microgel and a plurality of metal ions complexed thereto. The carbohydrate-templated microgel comprises a network copolymer molecule comprising a monoacrylate monomer, a crosslinking monomer, and a ligand monomer and wherein the microgel is prepared by the copolymerization of the monoacrylate monomer, the crosslinking monomer, and the ligand monomer in the presence of a carbohydrate or a carbohydrate derivative. The microgels have antimicrobial activity and allow for implementation of multiple, simultaneous mechanisms of antimicrobial action.
