Scientists have reported successful lab tests of “killer paper,” a paper coated with silver nanoparticles that could be used in food packaging to fight the bacteria that causes food spoilage. The silver-coated paper showed potent ability to kill off E. coli and S. aureus, two common causes of bacterial food poisoning. According to researchers, the material could promote longer shelf life and provide an alternative to current food preservation methods like irradiation. More details can be found in the American Chemical Society’sLangmuirjournal.
