Synthesis of Selenium Nanoparticles in the Presence of Oyster Polysaccharides and the Antioxidant Activity

Abstract:

A simple method for synthesis of nanoselenium using oyster polysaccharides as soft template was investigated. The uniform stable selenium polysaccharides were obtained under the condition of reaction temperature 40°C, reaction time 3 h-5 h, the content of oyster polysaccharides 400mg/L and the content of sodium selenite 1mM. The size distribution and morphology of the product were confirmed by scanning electronic microscopy (SEM) and tansmission electronic microscope (TEM). The antioxidant activity of nanoselenium polysaccharides were studied in vitro. The results showed that nanoselenium polysaccharide is an effective hydroxyl radical and DPPH radical scavenger.
