High refractive index haloalkyl-functional shell-core polymers and their use in light scattering immunoassays

摘要

Novel particle reagent for light scattering immunoassays are provided. The particle reagents are high refractive index shell-core polymers, having at least a partial surface coverage by a monomolecular layer of anionic surfactant, covalently bonded to compounds of biological interest. The novel particle reagents are particularly suited to protein immobilization by covalent bonding to the shell and are especially useful for light scattering immunoassays.
