英文摘要：
Nanomaterials, due to their unique properties, are widely used for developing electrochemical immunosensors with ultra high sensitivity and selectivity. It is an important facet that the nanoparticle based biolabel dramatically enhances the intensity of the electrochemical signal and leads to ultrasensitive hioassays. This review summarizes the application principle and present development of nanoparticlelabel in the construction of electrochemical immunoassay systems, and introduces recent progress of nanomaterial-based immunoassay biosensors.
