PCT No. PCT/FR96/00957 Sec. 371 Date Feb. 24, 1997 Sec. 102(e) Date Feb. 24, 1997 PCT Filed Jun. 20, 1996 PCT Pub. No. WO97/00896 PCT Pub. Date Jan. 9, 1997Latices of monodisperse magnetizable microspheres contain a hydrophobic polymer matrix and magnetizable fillers. The microspheres have a calibrated particle-size distribution and a size of around 0.1-5 micrometers, and the polymer matrix, produced by a dispersion polymerization method, includes polymer chains derived from at least one vinyl monomer. The latices are useful in biology, in particular, for diagnostic and affinity chromatography methods.
