A metallic silver particle is a silver particle what ever it is called, a nano-particle(metallic silver) or Colloidal Silver (metallic silver), silver aquasol(metallic silver). Only the size varies in the production of metallic silver particles. Now those of us who make our own at home can do so with a very low cost.
The statement “Smaller is always better” when it comes to silver nano-particles, is generally true, but only to a certain point. The actual answer was released in the data within American Biotech Labs ’new patent (# 7,135,195). (The link to the new patent can be found on the company website). On page 11 of the new patent, under the heading of “2. Size Analysis ”it states, “The smaller the average particle size, the greater the surface area and the greater the contribution of the particular surface chemistry. How
ever, if the particles are excessively small there can be a loss of stability and/or other interactions that negatively affect the product. ”This indicates that there is an optimal particle size for effectiveness of silver nano-particles. If the particle size becomes too small, the product loses effectiveness. The knowledge of optimal particle sizes has helped American Biotech Labs file and receive patents on what the company deems the most bio-active or most effective particle size. American Biotech Labs now owns the rights to these particular particle sizes, and no other company or person can legally make a similar product within approximately the next two decades.
