Gold Nanoparticle Conjugation

Gold Nanoparticle Conjugation

Gold nanoparticles, which are small particles of gold with a diameter of 1 to 100 nm, have high electron density, dielectric properties and catalysis, and can bind to a variety of biological macromolecules without affecting their biological activity. Because spherical gold nanoparticles have strong adsorption function to protein, they can bind to staphylococcal protein A, immunoglobulin, toxin, glycoprotein, enzyme, antibiotic, hormone, bovine serum albumin and so on. Therefore, it has become a very useful tool in basic research and experiments.
