Electrochemical DNA biosensor based on conducting polyaniline nanotube array.

Analytical chemistry - 1 Jul 2007

Chang Haixin, Yuan Ying, Shi Nanlin, Guan Yifu

Abstract excerpt

Most of the recent developments in ultrasensitive detection of nucleic acid are based on the gold nanoparticles and carbon nanotubes as a medium of signal amplification. Here, we present an ultrasensitive electrochemical nucleic acid biosensor using the conducting polyaniline (PANI) nanotube array as the signal enhancement element. The PANI nanotube array of a highly organized structure was fabricated under a...
