Abstract: Nanoparticle is a kind of material with at least one dimension in Nanometer scale, which has unique physical and chemical properties and is widely used in the fields of food and engineering. Intestinal Flora is involved in the regulation of human circulation and metabolism. The disturbance of Intestinal Flora may cause inflammatory reaction and chronic metabolic diseases. Nano titanium dioxide, Nano silver, Nano zinc oxide, Nano carbon nanoparticles and other nanoparticles have been proven to have good antibacterial properties, and can affect the intestinal flora of experimental animals. In this paper, the effects and mechanisms of various nanoparticles on intestinal microflora are summarized, which is helpful to provide a new idea for the safety study of nanoparticles.
