Detection of single-base mismatch at distal end of DNA duplex by electrochemical impedance spectroscopy.

Biosensors & bioelectronics - 15 Mar 2007

Ito Toshiyuki, Hosokawa Kazuo, Maeda Mizuo

Abstract excerpt

Herein, we report an anomalous electrochemical behavior of surface-bound DNA duplex that has single-base mismatches at its distal end. Single-stranded 15-base DNA was immobilized at its 5'end onto gold electrode surfaces. After hybridization with complementary or mismatched DNA, electrochemical i...
