Öğe DNA base sensor characteristics of polymeric-nanocomposite electrode(Taylor & Francis As, 2016) Ayazli, Sezen Kursun; Ekinci, Bilge Zabci; Ekinci, ErgunThe electrochemical synthesis of polyamline films was carried out by potential sweep method in sulfuric acid solution at the glassy carbon electrode. The electrocatalytic behavior to DNA bases (adenine and guanine) uric acid, and dopamine of polyaniline nanocomposite sensor modified with nano-gold particles was investigated by DPV technique. By systematically examining the effects of the possible parameters affecting he electrocatalytic performance of the relevant sensor, the optimal value for the each parameter was determined. The detailed electrocatalytic studies of the optimized sensor revealed that this sensor could be used as DNA base sensor for guanine in the presence of adenine, dopamine, and uric acid. Moreover, the performance of the relevant sensor in thermally denatured fish sperm DNA was quite satisfactory.

The influence of electropolymerization conditions on performance of the polytyramine film was examined to obtain the optimal experimental parameters. The voltammetric results demonstrated that polytyramine film obtained at the optimized conditions allowed penetration of large amounts of uric acid while blocking the permeation of electroactive (ascorbic acid, cysteine and oxalic acid) and non-electroactive interferents (lactose, sucrose and urea) through film in PBS. Therefore, it has been claimed that the polymeric film could be used as uric acid-selective membrane over a broad range of interference.
