Whenever we hear the term colloidal silver , what immediately comes into our minds is just a colloid or suspension of colloidal silver. Silver nanoparticles are colloidal particles of from less than one micrometer to a lot more than ten micrometers in diameter. While commonly described as' colloidal silver ', some are now made up of silver ion particles for their high percentage of pure silver oxide content. Some colloidal silver solutions include a little bit of other metallic compounds also; these compounds help in the processing of colloidal silver itself by keeping it from sticking with clots.

Colloidal silver nanoparticles release silver ions when they come in contact having an infectious object. Silver, together with many element particles, play a major role in killing bacteria, viruses and fungi by neutralizing their enzymes. Colloidal silver has been successfully used being an antimicrobial for many years now and the antimicrobial property of colloidal silver is still not fully understood. It is believed that colloidal silver may become a powerful natural and organic disinfectant by killing microorganisms. Silver kills microorganisms by producing free radicals that destroy the DNA of the microorganism, while causing no injury to the living cell.

A major study conducted at the University of Wisconsin demonstrated a strong antibioactivity towards selected bacteria. The analysis was done on a selection of aerobic and anaerobic microorganisms, which are typical in water, soil and drinking water. To be able to gauge the antibioactivity of colloidal silver , optical and spectroscopy techniques were applied. The outcomes showed that the antibacterial particle retention was significantly lower when compared with other non-organic materials which showed similar antibioactivity towards the tested microorganisms. The study also showed a substantial increase in the antifungal activity of colloidal silver once the suspension was in the pure water phase.

A colloidal silver nanofluid, as the name suggests, contains silver nanoparticles of different shapes and sizes held together by an organic surface potential. The top potential of the organic surface is measured utilizing the Beckley scale, which will be named after James H. Beckley who first used the scale to measure the outer lining potential of liquids and other substances. The size and shape of colloidal silver nanofluid nanoparticles be determined by its surface potential.
