title: Hydrophilic high-luminescent magnetic nanocomposites.
abstract: In this study, hydrophilic high-luminescent magnetic nanocomposites (LMNCs) composed of both fluorescent clusters (quantum dots, QDs) and magnetic nanoparticles were synthesized. The nanocomposites exhibited high luminescence and were easily separated in an external magnetic field. The LMNCs were capped with streptavidin (SA), and the SA on the surface of LMNC-SA composites was confirmed to be bioactive by competitive inhibition analytic methods. The fabricated LMNC-SA composites have potential application in biolabelling, bioseparation, immunoassay and pathogenic diagnosis.
