  • Title: Preparation and a time-resolved fluoroimmunoassay application of new europium fluorescent nanoparticles.
    Author: Hai X, Tan M, Wang G, Ye Z, Yuan J, Matsumoto K.
    Journal: Anal Sci; 2004 Feb; 20(2):245-6. PubMed ID: 15055946.
    Abstract:
    New silica-based europium fluorescent nanoparticles having surface amino groups were prepared by a covalent binding-copolymerization technique. In the nanoparticles, the fluorescent Eu3+ chelate molecules were covalently bound to silicon atoms to protect the nanoparticles from dye leaking in bio-applications. The amino groups on the surface of nanoparticles made the surface modification and bioconjugation of nanoparticles easier. The nanoparticles were characterized and developed as a new type of fluorescence probe for a highly sensitive time-resolved fluoroimmunoassay (TR-FIA) of human hepatitis B surface antigen (HBsAg).
