Abstract

Metal nanoparticle agglomerates in various forms may be utilized to promote infection control. Antiseptic substrates may comprise a base substrate and metal nanoparticle agglomerates adhered thereto. Metal nanoparticle agglomerates upon the antiseptic substrates may be contacted with a skin penetration, a skin injury, a burn, a site to be subjected to a skin penetration, or an active skin infection to provide infection control against at least one infective agent. The antiseptic substrates may also facilitate water purification in some cases. Antiseptic fluid formulations comprising a fluid medium having metal nanoparticle agglomerates dispersed therein may be configured for topical or oral use and may similarly afford infection control. Creams, ointments, balms, salves, gels, and liquids or liquid suspensions containing metal nanoparticle agglomerates may be effective for promoting infection control and/or for treating an active infection.
