title: Highly enhanced electrochemiluminescence of novel gold/silica/CdSe-CdS nanostructures for ultrasensitive immunoassay of protein tumor marker.
abstract: The highly enhanced electrochemiluminescence from a novel hybrid gold/silica/CdSe-CdS quantum-dot nanostructure has been reported for the first time, and successfully applied to develop an ultrasensitive ECL immunosensor for the detection of a protein tumor marker, carcinoembryonic antigen.
