摘要:A composition and method for inducing and inflicting damage to cell membranes of microorganism by inducing changes in membrane permeability caused by polycation-induced membrane pores. The control of Clostridium difficile spores with an efficacy of 99.99% on hard surfaces is provided. The invention includes the application of an evaporation-induced self-assembly, surfactant-mediated synthesis or self-condensing polymer, which forms a film which is both flexible on the surface as a nano-polymeric coating and with refractive index yielding a transparent coating. The polymeric matrix includes various biocidal polymeric cationic quaternary salts, one being a silyl quaternary having a kinetic zeta potential to disrupt bacterial spores functions. The polymeric matrix consist of multiple small molecule biocides as well as polymerics biocide combinations not otherwise seen to develop an surface topography of peaks and troughs in the nano range to resist bacterial adhesion factors and subsequent biofilm formation. The surfactants induce self-assembly film topography.
