Phil, I've looked at the paper from SCIENCE you reference, and it would
seem the preferential reactions you rely on for your conclusions only
occur at a temp of ~250deg. C.; not good for children and other living
things, e.g. cooked. Further, it is monomolecular silver IONS which
form the majority - ~85% - of silver particles (an ion is a particle
too, just dissolved in the water solute due to it's electrical valance.
Perhaps you know of more research in the area that responds to this
temperature problem and the multi-molecular state of the particles?
As a side issue to the above, one can use silver citrate, silver nitrate
(as is done in the science experiment you reference), and probably a few
others which are water-acid soluble and could yield multimolecular
silver particles, as for example the AgNP's, but the effects of some of
these (NO3) would be unhealthy to humans in higher concentrations.
Please comment; Thanks, Malcolm

Hi James,
AgNP stands for silver nanoparticle.
AgNP dissociates oxygen molecules into individual atoms which diffuse
throughout the atomic lattice structure of the silver particle.
The silver particle literally carries atomic oxygen around until it
meets a
pathogen. Then, the activated oxygen fries the pathogen on contact.
That's why it's important to keep those AgNP surfaces clean as possible.
The addition of CS enhances the performance of sols, anti-biotics, and
other apps, for sure, but some combinations I've seen hereabouts are
not net positive.
