SAT NANO spherical Au gold nanoparticle refers to a form of gold that has been processed into nanoparticles with a high level of purity. The purity of gold nanopowder refers to the absence of impurities or contaminants in the material. In the context of spherical Au gold nanoparticle, it means that the gold nanoparticles have been synthesized or processed in a way that minimizes the presence of other elements or compounds.We can supply spherical Au gold nanoparticle 20-30nm, 99.99%.

SAT NANO is one of the best supplier of spherical Au gold nanoparticle, we can offer different particle size like 20-30nm, 50nm, 100nm, Purity:99.99%,
Gold nanoparticles have very special optical properties of local surface plasmon polaritons (LSPR). When the frequency of incident light energy is the same as the electron frequency on the surface of rice particles, the surface electron group resonates. LSPR is not only related to materials, but also to the shape of particles, surrounding media, distance and symmetry between particles. Different types and sizes of Au nano Rice noodles will have different absorption peaks, and change the distance between particles, media, etc., causing the displacement of absorption peaks. For DNA or other biomolecule distance nanoparticles, 20-30nm gold nanoparticles are the best choice.
Au gold nano powder has agglomeration property, which can reduce the color. The gold nano powder was combined with the antibody to establish a micro agglutination test to detect the corresponding antigen. Like indirect coagulation, agglomerated particles can be directly observed with the naked eye.
