Abstract

This invention provides antibacterial and antiviral compositions and methods. The compositions possess prolonged and powerful antibacterial/antiviral functions under light exposure and even under completely dark conditions, while daylight exposures could recharge the functions repeatedly. In some embodiments, compositions of the invention can be employed in personal protective equipment (PPE) such as face masks, biologically self-cleaning air and water filters, medical devices, and products. The biocidal PPE can prevent transmission of infectious diseases such as Ebola and respiratory viruses. In some embodiments, compositions of the invention can be employed in food protectant materials to provide antimicrobial and antiviral bio-protection during food transportation and storage.
