Colloidal Silver Products or its salts are not generally recognized as safe for human use colloidal silver as a pesticide. These dictates highlight the need for rapid, simple, field-deployable methods for determining colloidal silver concentrations in liquid.  low concentrations, be user-friendly, compact, lightweight, capable of operation in microgravity, and employ non-toxic materials.

Colloidal Silver, These properties have led to tremendous range of applications of silver nanoparticles, such as antibacterial textiles and nanosilver-contained polymers used to make refrigerators, dish washers, rice cookers, plastic film, chopping boards, vacuum bottles, plastic pails, and garbage containers. Silver nanoparticles can also be used in various near field optical microscopy applications.

Silver is a liquid solution created using electrolysis to suspend pure, metallic elemental silver  attached to simple protein molecules, in distilled water. Colloids of silver should stay suspended, rather than sinking to the bottom, as the electric charge is stronger than gravity. Good quality colloidal silver should therefore not require shaking before use, or be dark in colour. Clear or pale yellow colloidal silver is the best as the particle size affects the colour of the solution and the larger particles produce a darker coloured liquid.

Silver Products the majority of the silver content is in the form of silver particles. True colloids will typically contain between 50 and 80 percent particles, while the balance will be silver ions. Colloidal silver has been remarkably effective natural antibiotic for centuries. colloidal silver can eradicate antibiotic-resistant microbes like MRSA, the Avian Influenza (bird flu), and Human Corona virus (SARS).

Silver Products have unique optical, electrical, and thermal properties and are being incorporated into products that range from photovoltaics to biological and chemical sensors. Examples include conductive inks, pastes and fillers which utilize silver nanoparticles for their high electrical conductivity, stability, and low sintering temperatures.
