Synthesis and characterization of new fluorescent nanoparticles

A novel kind of fluorescent nanoparticles (FNPs) has been prepared using a precipitation polymerization method. Methacrylic acid, trimethylolpropane trimethacrylate and azobisisobutyronitrile were used as functional-monomer, cross-linker and initiator, respectively. Compared with other fluorescent nanoparticles, the FNPs have the characteristics including low dye leakage and good photostability. The fluorescence microscopy imaging indicates that the FNPs can be used as fluorescent labels in bioanalysis.
