  • Method to use fluorescent magnetic polymer particles as markers in an immunoassay
    Patent number: 6013531
    Abstract: This invention provides a novel process of using magnetically responsive fluorescent polymer particles comprising polymeric core particles coated evenly with a layer of polymer containing magnetically responsive metal oxide as highly sensitive quantitative reagents for biochemical and immunological studies, wherein the fluorescent magnetic particles can serve as a marker for the number of particles. A wide variety of polymeric particles with sizes ranging from 1 to 100 microns can be used a core particles and transformed into magnetically responsive polymer particles. The surface of these magnetically responsive polymer particles can be coated further with another layer of functionalized polymer.
