Colloidal Silver: Coated or Uncoated?

Now that you realize that colloidal silver (silver particles) is the best option for antimicrobial effect, should you rely on coated or uncoated silver particles? This issue has been touched upon, but it is crucially important and should be revisited.

Coated is better for many reasons. It is the best option for colloidal silver because the coating prevents particles from clumping together and also makes them safer for human consumption.

Coating accomplishes many things:

  • particle size uniformity, so particles will be safe in the body and not get trapped in tissues
  • concentration, so it can be easily, conveniently, and inexpensively transported
  • stability, so it has a practically unlimited shelf life
  • stability in complex liquids (paints, soups, cans, drinks, etc).
  • a higher degree of safety, as most coated nanoparticles are


Not every coating is appropriate. The coating must be safe to ingest and chemically inert and not reactive. It must also incorporate the right dimensions and be permeable enough for ions to pass through at a feasible rate.

Coated Silver particles can be used in water treatments, soups, liquids, filters, or as an anti-infection agent dispersed in water. Presently, it is used in the International Space Station, hospitals, pools, and in several applications by big corporations like Samsung.
