Antiseptic applications of metal nanoparticle agglomerates

A method comprising:

• providing an antiseptic fluid formulation comprising a fluid medium having metal nanoparticle agglomerates dispersed therein;
• wherein the metal nanoparticle agglomerates comprise copper nanoparticles, wherein at least 80% or more of the copper nanoparticles range from about 50 nm to about 250 nm in size, and wherein the metal nanoparticle agglomerates are oxidized to form a reaction product comprising metallic copper, Cu2O and CuO species;
• and
• contacting the metal nanoparticle agglomerates with a skin injection site, a skin injury, a burn, a site to be subjected to a skin injection site, or an active skin infection to provide infection control thereto against at least one infective agent.

A water purification method comprising:

• providing an antiseptic substrate comprising a base substrate having metal nanoparticle agglomerates adhered thereto;
• wherein the metal nanoparticle agglomerates comprise copper nanoparticles, wherein at least 80% or more of the copper nanoparticles range from about 50 nm to about 250 nm in size, and wherein the metal nanoparticle agglomerates are oxidized to form a reaction product comprising metallic copper, Cu2O and CuO species;
• contacting the metal nanoparticle agglomerates with water containing at least one infective agent;
• and
• inactivating at least a portion of the at least one infective agent with the metal nanoparticle agglomerates.

A method comprising:

• contacting a plurality of metal nanoparticle agglomerates with a skin surface;
• and
• inactivating at least one infective agent with the metal nanoparticle agglomerates while contacting the skin surface;
• wherein the metal nanoparticle agglomerates comprise copper nanoparticles, wherein at least 80% or more of the copper nanoparticles range from about 50 nm to about 250 nm in size, and wherein the metal nanoparticle agglomerates are oxidized to form a reaction product comprising metallic copper, Cu2O and CuO species.

An antiseptic fluid formulation comprising:

• a fluid medium;
• and
• metal nanoparticle agglomerates dispersed in the fluid medium;
• wherein the fluid medium is a cream, ointment, salve, gel, liquid, or liquid suspension suitable for contacting a skin surface or for oral use;
• and
• wherein the metal nanoparticle agglomerates comprise copper nanoparticles, wherein at least 80% or more of the copper nanoparticles range from about 50 nm to about 250 nm in size, and wherein the metal nanoparticle agglomerates are oxidized to form a reaction product comprising metallic copper, Cu2O and CuO species.
