Anti-viral Paint That Kills Flu Developed

A remarkable new anti-viral polymer can be applied like paint and could help reduce the spread of germs in public areas and hospitals. The "biocidal paint" was developed by MIT's Alexander Klibanov. In a demonstration, a regular glass slide and another one coated with alkylated PEI "paint" were sprayed with aqueous suspensions of Staphylococcus aureus cells, and then incubated. Some 200 bacterial colonies were seen on the unprotected slide - and only 4 on the protected one.
