Özet

Described here are the chronocoulometric and voltammetric parameters for methylene blue [3,7-bis(dimethylamino)phenothiazin-5-ium chloride, MB] on binding to DNA at carbon paste electrode (CPE) surface. MB, which interacts with the immobilized calf thymus DNA was detected by using single stranded DNA modified CPE (ssDNA modified CPE), bare CPE and double stranded DNA modified CPE (dsDNA modified CPE) in combination with chronocoulometry and differential pulse voltammetry (DPV) techniques, The effect of ionic strength to the behavior of MB with dsDNA and ssDNA was also studied by means of voltammetry. These results demonstrated that MB could be used as an effective electroactive hybridization indicator for DNA biosensors. Performance characteristics of the sensor are described, along with future prospects. (C) 2002 Elsevier Science B.V. All rights reserved.
