Nanoparticles: Everlasting Germ Killer, In Paint, Fabric, Plastic And More

Good news! We presume it is fairly harmless to human health!

Best of all it acts permanently for a long time without refilling etc.

"Nanosono, a startup based in ... Israel, says its doing exactly that. It has developed nanoparticles – less than a millionth of a millimeter – made of zinc oxide and copper oxide. ...

The nanoparticle, known as Quactiv, was originally designed as a powdered additive for fabric and then to paint, to reduce the number of hospital deaths from from infection-related diseases.

“You need one kilogram of Quactiv in two tonnes of paint to get the antimicrobial action,” ... That’s a concentration of just 0.0005 per cent. It’s cost-effective, non-toxic and environmentally friendly ...
Two mechanisms of action work together. One is the electrostatic interaction between the positive charge of the nanoparticles and the negative charge of the microbes. The second is the release of specific free radicals (reactive oxygen molecules) that destroy the functionality of the microbes. ..."
