摘要
A biocidal article, includes a surface including a plurality of polymers covalently attached to the surface. The polymers include biocidal cationic groups. The polymers have a molecular weight distribution or polydispersity less than 3. A grafting density of the polymers on the surface is controlled, average degree of polymerization of the polymers is controlled and repeat units of the polymers are- chosen to provide a predetermined charge density arising from the cationic groups. A method of analyzing biocidal activity of biocidal surface agents includes the steps: attaching a plurality of chemical entities to one or more surfaces so that at least one physiochemical property is varied, each of the chemical entities comprising at least one biocidally active component; and exposing the chemical entities to at least one biological agent to determine the effect of the at least one physiochemical property upon biocidal activity. The biocidal activity can, for example, be antibacterial activity or sporicidal activity. The at least one physiochemical property can, for example, be varied in a preferably systematic manner.
