Abstract
In this paper, a DNA aptamer was detected by electrochemical DNA sensors. To enhance the sensitivity and selectivity, the working electrode surface of the electrochemical sensor was modified by a synthesis of poly-pyrrole nanowires. Characterization of poly-pyrrole nanowire was verified by SEM images. The evaluation of DNA sensors was implemented using EC301 Potentiostat from SRS. The sensor can detect the DNA concentration as low as 10−12 mol/l. A series of measurement were conducted, which showed the relationship between DNA concentrations and peak current.
