Hydrogels made from epsilon-poly-L-lysine-graft-methacrylamide (EPL-MA) have been found to have impressive wide spectrum antimicrobial activity against both bacteria (specifically Escherichia colt, Pseudomonas aeruginosa, Serratia marcescens and Staphylococcus aureus) and fungi (specifically Candida albicans and Fusarium solani). The EPL-MA hydrogel also possesses in vitro biocompatibility and EPL-MA solution is relatively non-hemolytic: the concentration needed for onset of human red blood cell (hRBC) hemolysis is 12,500 mu g/mL so that the selectivity for the pathogenic microorganisms over hRBCs is 230-1560. Further, EPL-MA hydrogel can be conveniently ultraviolet-immobilized onto plasma-treated plastic surfaces to form thin highly adherent antimicrobial hydrogel coatings for medical devices and implants.
