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’s
Langmuir journal.
