Polystyrene- and albumin-based magnetic microspheres for red blood cell separation were modified and characterized by scanning electron and atomic force microscopy. Albumin microspheres show higher coupling efficiency with the protein, and protein-modified albumin microspheres bind the red blood cells more efficiently than the polystyrene-based microspheres.
