Duuuuaawwwwhhhh! The article was written in 2001 before the the Perfect Colloidal Silver Products came along, they admit that silver atoms are a possiblity, but not for them and certainly not for you, because they and yourselves are in the nanoparticle production business, whether you admit it or not, you back websites that sell 20 PPM products or Do It your Self kit sellers that think you know everything about Colloidal Silver production.
Denial of products that your pea brains can not make.
