Abstract:
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 new flourescent nanoparticles have the characteristics including low dye leakage and good photostability. The fluoroimmunoassay indicates that the FNPs can be used as fluorescent labels in bioanalysis.
