Gold Nanoparticles


Gold Nanoparticles


Gold nanoparticles are between 1 and 100 nm. It exhibits different colors with particle size, high electron density, dielectric properties and catalysis. The high electron density gives it good contrast under the electron microscope and is therefore well suited as a marker for electron microscopy testing.


The negative charge on the surface of the nano-gold particles is firmly combined with the positive charge group of the protein due to electrostatic adsorption. After adsorption, the biomolecule is not denatured and can be combined with various biological macromolecules without affecting their biological activity, such as staphylococcal protein, immunoglobulin, Toxins, glycoproteins, enzymes, antibiotics, hormones, bovine serum albumin, etc.
