A household paint that kills germs

Filed under: — By Aviran Mordo @ 6:15 pm

Researchers at Rice University and City College of New York have come up with a way to embed silver nanoparticles in vegetable oil-based paint. Early tests show that the material exhibits “efficient antibacterial activity” toward E. coli and Staphylococcus aureus.

Silver’s antibacterial properties have been known since the age of the Roman Empire, but making nano-sized particles (nano particles measure less than 100 billionths of a meter long) and then fixing them in paints and coatings has typically been expensive and time consuming. The Rice and CCNY researchers devised a hydrocarbon soup that in turn helps form raw materials into nano-sized particles.
