Multiple signal amplification electrochemiluminescent immunoassay for Sudan I using gold nanorods functionalized graphene oxide and palladium/aurum core-shell nanocrystallines as labels

A novel competition-type electrochemiluminescent (ECL) immunosensor for detecting Sudan I was fabricated with palladium/aurum core-shell nanocrystallines (Pd/Au CSNs) as signal probes and gold nanorods functionalized graphene oxide (GNRs/GO) as substrates.331
