Selenium Nanocolloid

Selenium is a toxic material that is chemically similar to sulfur and tellurium. There are many applications for this element today, such as some steels alloys and selenium rectifiers. Selenium is one of the essential elements for human health as well as one of the enormous biocatalysts and components of enzymes necessary to improve immune function and anti-cancer effects. Selenium and silver nanoparticles are substances that have been reported to have antimicrobial, antifungal, and antiparasitic properties. However, there are problems with the drug's use and treatment with selenium. For this reason, nanotechnology proposes the use of this element in nano-scale for the purpose of preserving the properties of this element for food and pharmaceutical applications. Selenium nanoparticle as a potent antioxidant is much less toxic than selenium and it also has a high potency in clearing free radicals and can therefore be used as a natural antioxidant. Suspended selenium nano-colloid contain selenium nanometer particles in a given solution. Due to its high surface area to volume ratio, it has antibacterial and antioxidant applications and is used in cosmetics.
