The image above, from Stanford University's Engineering Department, shows isolated 2 nm and 5 nm silver nanoparticles, inside the nanoparticles you can see the atoms on the surface of the nanoparticle spheres.
There are hundreds and even up to tens of thousands of individual atoms in a 5nm particle. What is not depicted are nanoparticles that are larger than 5nm, which sizes can exceed 200nm, such large particles may contain 250,000 to almost Millions of Atoms.
This clearly illustrates that an atom of silver cannot be 239 nm, as has been stated by other researchers. When you can easily see silver atoms on a nanoparticle that is 2 nm in size, obviously the atoms are smaller than 2 nm.
When looking at size measurements, an Angstrom (Symbol Å) is about the same size as an Atom, 10 Hydrogen Atoms (Angstroms) equal 1 nm. Therefore, atoms are typically ten times smaller than a one-nanometer particle. Proper measurement of atomic size particles is done in angstroms. One atom equals one angstrom in size.
Many producers distort the facts!
We found that many contradict their particle size claims and have created their terms and definitions.
The fact they are not willing to admit that they use chemicals (Even though the FDA reported that they do use chemicals, and hundreds of patents prove that chemicals are used)should immediately raise a Red Flag, and everything they state should be questioned. Again, just because they have their own laboratory does not make them an Honest Authority on colloidal products since they will report what best suits their market share.
