Antibacterial Composition, Antibacterial Cases and Accessories for Handheld Electronics, and Method of Making Antibacterial Cases for Handheld Electronics

A method of making an antibacterial case for a handheld electronic device, which comprises:

• providing a polymer matrix;
• melting said polymer matrix by heating said polymer matrix above a melting point of said polymer matrix;
• admixing at least one part per million of silver containing nanoparticles to create a silver nanoparticle polymer matrix;
• and
• injecting said silver nanoparticle polymer matrix into a mold to form a cast, said cast being shaped to receive the handheld electronic device.

A method of making an antibacterial case for a handheld electronic device, which comprises:

• providing a varnish, said varnish being adherable to a material of a case when cured;
• admixing at least one part per million of silver containing nanoparticles into said varnish to create a silver nanoparticle varnish;
• coating a surface of the case to be handled during use of the handheld wireless electronic device with the silver nanoparticle varnish;
• and
• adhering the silver nanoparticle varnish to the surface of the case by curing the silver containing varnish.
