聚吡咯电化学DNA生物传感器的研究进展

ue to the special structure and excellent physical and chemical properties, the conducting polypyrrole is becoming a new material for fabricating electrochemical DNA biosensor and provides a new thread for the development of genolelectronics in future. The paper reviewed the practical applications of polypyrrole in electrochemical DNA biosensor in the recent years, discussed the selection and modification of electrodes and immobility strategies of DNA probe in the fabrication of the polypyrrole-based electrochemical DNA biosensor. Meanwhile, combined with the microarray, microfluidic technique and nano-materials, the future research directions and applications of polypyrrole-based electrochemical DNA biosensor are discussed and prospected.
