Carboxylated polystyrene suspensions with narrow particle-size distribution have been synthesized by seed polymerization in a mixture containing organosilicone surfactants. The characteristics of the particles such as average particle diameter (5,8 μm), zeta-potential (–31,6 mV) and functional group quantity were determined. We have developed a technique that makes it possible to homogeneously stain the microspheres with a fluorescent dye across the whole body of their suspension and to reach various emission intensity. Mixtures of these microspheres might make these particles helpful for multiplex immunofluorescent bead-based analysis.

 

Key words:  immunofluorescent analysis,  narrow particle-size distribution,  organosilicone surfactant,  polystyrene microspheres,  seed polymerization.
