Abstract: Selenium nanoparticles (SeNPs) is a kind of elemental selenium particles at nano-size scale, possess great potential in their application in the fields of agriculture, food, medicine and etc, thanks to the unique properties and excellent biological activities of these nanoparticles. Polysaccharides with their excellent bio-compatibility, good stability and various bio-activities, are helpful to the stable preparation and functional decoration of SeNPs, which might improve the physicochemical properties and functional activities of the nano systems. In this paper, the preparation, bio-activities and application of polysaccharide-SeNPs became the focus of attention. Briefly, the methods and technology utilized to synthesize the SeNPs through chemical reduction were summarized and then, the coordination and influence of polysaccharides upon these nanoparticles were analyzed. After that, the antioxidant capacity, immunomodulatory activities and anti-tumor abilities of the polysaccharide-SeNPs were reviewed, while the application of the polysaccharides-nano-system in the food-related fields was introduced. Finally, the opportunities and challenges of the polysaccharide-SeNPs were discussed when the nanoparticles were utilized to improve the food nutrition. The review might provide theoretical basis and research ideas for the research & development of polysaccharide-SeNPs.
