Abstract
Latices 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.
