Whenever we hear the definition of colloidal silver , what immediately comes into our minds is just a colloid or suspension of colloidal silver. Silver nanoparticles are colloidal particles of from significantly less than one micrometer to significantly more than ten micrometers in diameter. While commonly referred to as' colloidal silver ', some are now composed of silver ion particles because of the high percentage of pure silver oxide content. Some colloidal silver solutions include a tiny amount of other metallic compounds also; these compounds aid in the processing of colloidal silver itself by keeping it from sticking to clots.Colloidal silver nanoparticles release silver ions if they come in contact with an infectious object. Silver, along with other element particles, play a significant role in killing bacteria, viruses and fungi by neutralizing their enzymes. Colloidal silver has been successfully used as an antimicrobial for decades now and the antimicrobial property of colloidal silver remains not fully understood. It is thought that colloidal silver may act as a highly 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 injury to the living cell.An important study conducted at the University of Wisconsin demonstrated a solid antibioactivity towards selected bacteria. The study was done on a selection of aerobic and anaerobic microorganisms, which are typical in water, soil and drinking water. In order to assess the antibioactivity of colloidal silver , optical and spectroscopy techniques were applied. The outcome revealed that the antibacterial particle retention was significantly lower in comparison to other non-organic materials which showed similar antibioactivity towards the tested microorganisms. The study also showed a substantial escalation in the antifungal activity of colloidal silver when 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 outer lining potential of the organic surface is measured utilizing the Beckley scale, that is 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.For more details check out koloidne striebro (colloidal silver).
