Abstract
A method of bonding an antimicrobial cationic polyelectrolyte to the surface of a substrate is described, wherein the antimicrobial thus attached to the substrate provides the substrate with antimicrobial properties, and at least a portion of the bonded antimicrobial is substantially non-leachable during normal conditions of use and storage. A method of manufacturing an antimicrobial material is described which comprises exposure of the substrate to a solution of antimicrobial cationic polyelectrolyte, followed by drying the exposed substrate thoroughly to impart a non-leaching property to at least a portion of the antimicrobial cationic polyelectrolytes.
