Why are you acting the way pharmaceutical companies act towards Colloidal Silver ?
This is a well written article, after reading their website it appears to me that you are not only over reacting, but stretching the facts, they admit that a single nanoparticle is 3900 atoms in size, the larger the nanometer the larger the atoms content, you are relating a 250,000,000 atom particle to a single nanometer, they do not state that, the specifically mention that a 300 nm particle could be about 250,000,000 atoms in size.
Furthermore they have proof from some Colloidal Silver producers with an Phd:
Atoms Reported by: Francis S. Kelly and George Maass PhD wrote an article: Ions, Atoms and Charged Particles
A single silver atom can be considered to be an atomic sized particle of metallic silver. It is the smallest size of silver matter that exists. The diameter of a single silver atom is 0.288 nm. While it is theoretically possible to have a particle of metallic silver that consists of a single atom, in practice particles are much larger and consist of many atoms.
Just for reference, a particle one nanometer in diameter would consist of 31 silver atoms, and a 5 nm diameter particle would be about 3900 atoms while a 20 nm diameter particle would contain about 250,000 silver atoms. The particle size typically observed in Colloidal Silver has been measured in the range of 5 to 200 nanometers. Such measurements are performed using a Photon Correlation Spectrometer (PCS) that can measure down to 1 nm. In our laboratory a Malvern Zetasizer 3000HS is used to make such measurements” http://www.silver-colloids.com/Papers/IonsAtoms&ChargedParticles.PDF
These scientist acknowledge that a single silver atom is possible.
Why the anger, why the hate, its understandable that many get frustrated because the process is unknown to them, is that why you are so in denial? They will not tell you how its done?
