and Ag NPs capped with poly (methacrylic acid) led to the formation of a col-ored thin film possessing antimicrobial properties. Lee et al. reported coating of stable Ag NPs onto cotton fabric by soaking in ethanolic solutions of AgNO3and butylamine. The Ag NP coated
cotton fabric exhibited excellent bactericidal effects on pathogenic bacteria without causing direct skin irritation. Zhao et al. pro-duced nanostructured silver coating layers on polyimide films by treatment with aqueous KOH and AgNO3, followed by thermal treatment at 200◦C or higher temperatures. Further modifica-tion of the gold-coated silver layers with n-dodecanethiol led to
hydrophobic surfaces.
