Your information is a nice story you believe but it stops there with you ... here try wikipedia(http://en.wikipedia.org/wiki/Silver_nanoparticles)

You may want to read the part about health concerns which are quite different to natural silver

Quote:

Exposure to silver nanoparticles has been associated with "inflammatory, oxidative, genotoxic, and cytotoxic consequences"; the silver particulates primarily accumulate in the liver.[5] but have also been shown to be toxic in other organs including the brain.[6]


Silver loaded anti-bacterial paint is produced by the wet process to because they want the collide base on the nano-particles to bind into the paint.

As nano-technology has become a bad word to people like you they are investigating "green" more natural ways to do it but no commercialisation has been achieved.

Examples of attempts to green up the process:

So if you want to fool yourself that silver nano-particles are somehow natural knock yourself out.


I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
