In this study, micron-sized poly(styrene-co-glycidyl methacrylate) (PSt-GMA) fluorescent microspheres of 5.1microm in diameter were synthesized via dispersion polymerization of styrene and glycidyl methacrylate in the presence of 1,4-bis(5-phenyloxazol-2-yl) benzene (POPOP), which provided surface functional groups for covalent immobilization of enzymes.

The involvement of upper electron-excited states in bacterial bioluminescence process was studied with excitation energy-accepting molecules. The fluorescent aromatic compounds, anthracene and 1.4-bis(5-phenyloxazol-2-yl)benzene, were chosen. Energies of their lowest excited singlet states are higher than the energy of the analogous
