Which nanomaterial is used to prevent the WBC from taking gold nanoparticles as an antigen?

Gold nanoparticles are typically smaller than several hundred nanometers in size, comparable to large biological molecules such as enzymes, receptors, and antibodies. With the size of about one hundred to ten thousand times smaller than human cells, these nanoparticles can offer unprecedented interactions with biomolecules both on the surface of and inside the cells. Therefore silver nanoparticles can be used as they are antimicrobial in function thereby the white blood cells are prevented from taking au nanoparticles as an antigen.
