SPHERO Fluorescent Particles

SPHERO Fluorescent Particles

  •  Beneficial to bioimaging and biosensing applications 
  • Uniform and stable fluorescence 
  • Available with functional groups for covalent binding of antigens or antibodies

The SPHEROTM fluorescent microparticles are prepared by either staining polystyrene particles with a fluorophore solution or by polymerizing a fluorophore in styrene in the presence of polystyrene core particles. As a result, a wide variety of fluorescent particles can be prepared ranging in size, type of fluorophore, fluorescence intensity and surface functional groups. The fluorophores chosen for use in the preparation of SPHEROTM fluorescent particles are water insoluble and therefore are very stable. These fluorophores, once incorporated into the particles, do not leach and their color and fluorescence remains stable for long periods of time under proper storage conditions. The excitation and emission spectra of some of the fluorophores used in the SPHEROTM fluorescent particles are shown in Figure 1.
