An antibacterial composition is formed from a polymer matrix that includes silver nanoparticles. The antibacterial composition can be used to provide surfaces that are to be touched. The antibacterial composition is particularly useful for forming cases for handheld electronic devices such as mobile telephones, smartphones, tablet computers, remote controls, and game controllers. A method of manufacturing items formed the composition can create materials with homogenously dispersed silver nanoparticles. Another process can be used to add antibacterial properties to existing surfaces.
