title: Specific immunoreaction-induced controlled release strategy for sensitive impedance immunoassay of a cancer marker.
abstract: A simple and facile impedance immunoassay strategy for sensitive detection of alpha-fetoprotein (AFP), as a model cancer marker, was developed by using target-induced release of nanogold particle-labelled anti-AFP antibodies from polyvinylpyrrolidone-coated magnetic carbon nanotubes.
