Selenium nanoparticles with improved biological effects

摘要

Novel methods for biological effective, stable amorphous and monoclinic selenium nanoparticles are disclosed. They are prepared by reacting selenium source with a reducing agent or an oxidative agent in an aqueous media at a temperature between 0-100° C. in the presence of selenium binding polymer molecules such as poly/oligopeptide acids or peptone or nucleic acids or poly/oligosaccharide or their mixtures.
