"I wonder what method the researchers used to produce silver particles, since they reported that the smallest size particle is 3 nanometers, which is much, much larger than the 0.65 nanometer particles that are found in the best true
Colloidal Silver products."
{The above does not state if this particle size in nanometer (nm) is for RADIUS or for DIAMETER, this is the rather curious thing I've always noticed when discussion of size of particles comes up, if it is in reference to radius or diameter}
Silver has an atomic radius of 0.144 nm. Double for diameter.
Ionic silver has an atomic radius of 0.115 nm. Double for diameter.
Non-ionic silver can be manufactured to about 1.0 nm radius, that's 7 atoms, none smaller is known that I've read about, that is until coming to this forum.
You stated above that you know of a 0.65 nm size particle. Is that radius or diameter? The problem with the 0.65 size is that when it is divided by atomic radius of 0.144 you get 4.5 atoms, impossible to have half an atom. However if you double the 0.65 to 1.3 & divide by 0.144 then you get an even 9 atoms, this suggesting somebody got their numbers mixed up by halving 1.3 to 0.65 because they didn't know how to read atomic radii from the Periodic Table.
Of course all Ionic-silver particles are 0.115 nm because ions cannot agglomerate.
So far from all I can see, is that the smallest actual nano-particle of non-ionic agglomerated atoms that can be manufactured is the ~1.0 nm nano-particle of 7 atoms.
