The Importance of Particle Size

Small particle size is a subject with a very important large significance in relation to colloidal silver. The size of the silver particles in colloidal silver products makes a difference in being able to effectively travel in the fluid environment of the body. When the particle size/product effectiveness relationship is understood, the difference in the value of various products is more easily understood.

PPM (parts per million) is the common measure of the strength of colloidal silver products. It indicates the concentration of silver. Obviously, PPM is an important consideration in your selection of a product. At least as important, though less understood is particle size. The following paragraphs may enlighten you somewhat and aid in understanding the importance of particle size in colloidal silver and colloidal gold.

Imagine an 8-ounce glass of pure water into which is placed a sphere of silver an inch in diameter. It has a given surface area. Only the surface of the sphere (the particle) has any effect on the properties of this glass of water. If pathogens are introduced into the water and come in contact with the sphere, they are killed. To increase the germ-killing effectiveness of this given amount of silver, we have to expose more of the metal to the water. We could do this by cutting the sphere in half, exposing the cross-section of both halves. Guess what? Although we have the same amount of silver, we have now increased the germ-killing potential. Although the concentration (ppm) of the silver has not been altered, we have significantly increased the particle size. If we then slice these two particles in half, making four particles, we increase the amount of surface area exposed to the water even further, increasing yet again the effectiveness of the still constant amount of silver in the water. This illustration serves to prove that particle size is inversely proportional to its germ-killing effectiveness.

In a colloid, the particles are held in suspension and permeate the medium (in this case, water) uniformly. The smaller these particles are, generally the better, because the increased particle surface area can potentially kill more germs. Additionally, smaller particles stay in suspension better, making the colloid more stable. Smaller particles can better penetrate the body's deep tissue where circulation is minimal. In our Advanced Colloidal Silver, the particles are extremely small by design. Our Advanced Colloidal Silver has a mean average particle size of approximately 2 nanometers in diameter. A nanometer (nm) is a ionth of a meter. [Approximately 1 ion nm size particles could be arranged side by side on the cross-section of a human hair!]
