The present invention relates to a loaded reactive nanoscale latex particle synthesized from mixture of monomers containing water insoluble monomers, at least two ethylenically functionalities monomers, halo-aromatic-polyethyleneglycol-methacrylate, polyethyleneglycolacrylate containing macromonomers, and up to 10 wt % other ethylenic monomers different from above monomers. The reactive halo-aromatic groups on the surface of latex particle are servable as linkers to react with peptides, antibodies, nucleic acids, ligands or other biomolecules.
