Abstract

Colloidal-sized paramagnetic particles are formed with affinity ligands directly adsorbed to their surface. The colloidal-sized particles can form a colloidal disperse phase which is distributed through an aqueous dispersion medium to form a biological magnetic fluid. The fluid can be used to selectively separate cells from a cell mixture.
