What Techniques are Used to Attach Antibodies to Nanoparticles?
Several techniques are employed to attach antibodies to nanoparticles, including covalent bonding, adsorption, and biotin-streptavidin linkage. Covalent bonding involves creating strong chemical bonds between the antibody and the nanoparticle, while adsorption relies on weaker physical interactions. The biotin-streptavidin system provides a robust and highly specific attachment method.
