Researchers at Northwestern University have discovered new ways of utilizing the properties of naturally occurring polyphenols found in green tea, red wine and dark chocolate. Dissolving polyphenol powders in water with a small amount of salt instantly produces transparent coatings that kill bacteria on contact, have antioxidant qualities and are non-toxic. The sticky nature of polyphenols and the low cost of materials could open the door to a wide range of uses for these coatings.
