When we hear the word colloidal silver , what immediately makes our minds is a colloid or suspension of colloidal silver. Silver nanoparticles are colloidal particles of from significantly less than one micrometer to a lot more than ten micrometers in diameter. While commonly called' colloidal silver ', some are actually made up of silver ion particles for their high percentage of pure silver oxide content. Some colloidal silver solutions include a small amount of other metallic compounds also; these compounds aid in the processing of colloidal silver itself by keeping it from staying with clots.

Colloidal silver nanoparticles release silver ions if they interact having an infectious object. Silver, along with various other element particles, play a significant role in killing bacteria, viruses and fungi by neutralizing their enzymes. Colloidal silver has been successfully used being an antimicrobial for decades now and the antimicrobial property of colloidal silver is still not fully understood. It's believed that colloidal silver may act as an effective natural and organic disinfectant by killing microorganisms. Silver kills microorganisms by producing free radicals that destroy the DNA of the microorganism, while causing no harm to the living cell.

A significant study conducted at the University of Wisconsin demonstrated a strong antibioactivity towards selected bacteria. The analysis was done on a range of aerobic and anaerobic microorganisms, which are typical in water, soil and drinking water. In order to measure the antibioactivity of colloidal silver , optical and spectroscopy techniques were applied. The outcomes indicated 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 significant increase in the antifungal activity of colloidal silver once the suspension was in the pure water phase.

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