Biocidal Paint

Pruned: Biocidal Terrain: There is now apparently a paint that can destroy the flu virus on contact.

“A surface coated in spiky polymer molecules destroys the flu virus at a touch,” Scientific American reported last month. This nontoxic substance does so by “gouging holes in a microbe’s cell wall and spilling out its contents. The polymer molecules stay rigid because they are all positively charged and therefore repel each other, like strands of hair standing on end from a static charge. The spikes have sufficiently few charges, however, that they can breach bacterial walls, which repel strongly charged molecules. The polymer probably neutralizes flu because the virus has an envelope around it suitable for spearing.”
