文摘

Multifunctional Fe3O4-Au nanocomposites offered good conductivity, easy bioconjugation and convenient separation. Dual-stabilizers-capped CdTe QDs with excellent ECL performance served as signal labels. A sanwiched ECL nano-immunosensor with enhanced sensitivity was presented for a general application in bioassays.
