PEG-COOH

nanomag®-D particles with diameters of 130 nm, 250 nm and 500 nm are designed with PEG-COOH groups on the surface for the covalent binding of proteins, antibodies or other molecules, e.g. by carbodiimide chemistry (see technote 200). The functionalized nanomag®-D particles can be separated with permanent magnets and are supplied in water without any surfactants.
