A streptavidin-functionalized silver-nano-particle-enriched carbon nanotube is designed as a trace tag for ultrasensitive multiplexed detection of tumor markers by combination with silver-deposition enhancement and electrochemical stripping analysis of silver nanoparticles on a disposable immunosensor array. The excellent analytical performance of this method demonstrates that the functionalized nanohybrid is a promising and versatile amplified probe for application in biotechnology.
