Superuniform spherical gold nanoparticles

Gold nanoparticles, with their excellent conductivity, stability, biocompatibility, and surface optical properties, have irreplaceable roles in optics, catalysis, electronics, immunodiagnosis, biosensors, biological imaging, and drug delivery. At present, sodium citrate reduction method is a classic method for preparing gold nanoparticles, but the prepared gold nanoparticles have irregular shapes, and their uniformity and stability are not ideal. Therefore, the preparation of gold nanoparticles with different particle sizes that have regular shapes, uniform particle sizes, good dispersibility, and stable properties is an urgent problem to be solved in current production. We first used chemical reduction method to prepare 5-15 nm small diameter super uniform spherical gold nanoparticles. Using small diameter spherical gold nanoparticles as seeds, we used seed growth method to prepare 20-200 nm super uniform spherical gold nanoparticles. The spherical gold nanoparticles prepared by this method have uniform particle sizes, regular shapes, and uniform dispersion; Depending on the particle size, it presents different colors in aqueous solution, such as orange, red, magenta, and brick red.
