The surfaces of pencil graphite electrodes (PGEs) were decorated with zinc oxide nanowires (ZnO NWs) for the electrochemical detection of nucleic acids. ZnO NWs were synthesized through simple hydrothermal method. PGEs decorated with ZnO NWs (ZnO NW/PGEs) were electrochemically characterized through cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) following morphological characterization through transmission (TEM) and scanning electron microscopy (SEM). Enhanced sensor response obtained using ZnO NW/PGEs contrary to the bare PGE (control) samples. Our preliminary results simply reveal the potential of combining ZnO NWs with disposable sensor technology for the electrochemical detection of DNA.

Zinc Oxide Nanowire Photodetectors with Single-Walled Carbon Nanotube Thin-Film Electrodes Ates, Elif Selen; Kucukyildiz, Seyda; Ünalan, Hüsnü Emrah (2012-10-01) In this study, transparent and flexible zinc oxide (ZnO) nanowire ultraviolet (UV) photodetectors prepared via a solution-based method in which single-walled carbon nanotube (SWNT) thin films were used as transparent electrodes are reported. The photoresponse current was found to be in proportion with the ZnO nanowire density, and the nanowire density could be tuned to increase the photocurrent by a factor of 300. The decay time for the fabricated photodetectors was found to be as low as 16 s. This study su...
Electrochemical polymerization of 1-(4-nitrophenyl)-2,5-di(2-thienyl)-1 H-pyrrole as a novel immobilization platform for microbial sensing Tuncagil, Sevinc; ODACI DEMİRKOL, DİLEK; Varis, Serhat; TİMUR, SUNA; Toppare, Levent Kamil (2009-09-01) Two types of bacterial biosensor were constructed by immobilization of Gluconobacter oxydans and Pseudomonas fluorescens cells on graphite electrodes modified with the conducting polymer; poly(1-(4-nitrophenyl)-2,5-di(2-thienyl)-1 H-pyrrole) [SNS(NO2)]. The measurement was based on the respiratory activity of cells estimated by the oxygen consumption at -0.7 V due to the metabolic activity in the presence of substrate. As well as analytical characterization, the linear detection ranges, effects of electropo...
Effective mass and peculiarity of optical properties of Cadmium Sulfide nanoparticles Muradov, M. B.; Eyvazova, G. M.; Turan, Raşit; Maharramov, A. M. (2008-12-01) X-ray diffraction data, electron microscope and optical properties of cadmium sulfide nanoparticles were analyzed. It is shown that the value of the reduced effective mass of charge carriers in nanoparticles differs from bulk crystals. Changes of effective mass and "red shift" in values of band gap are explained by the occurrence of additional electronic potential in nanoparticles.
Miscibility of methylmethacrylate-co-methacrylic acid polymer with magnesium, zinc, and manganese sulfonated polystyrene ionomers Alkan, C; Yurtseven, N; Aras, L (2005-01-01) The miscibility of methyl methacrylate-co-methacrylic acid polymer (MMA-MAA) with metal neutralized sulfonated polystyrene ionomers was investigated by viscometry, differential scanning calorimetry (DSC), and Fourier transform infrared radiation spectroscopy (FTIR) techniques. Polystyrene (PS) was sulfonated by acetic anhydride and sulfuric acid and the sulfonation degree was found to be 2.6 mole percent, and 2.6 mole percent sulfonated polystyrene was neutralized by Mg, Zn, and Mn salts. The miscibility be...
Fully metal oxide charge selective layers for n-i-p perovskite solar cells employing nickel oxide nanoparticles Icli, Kerem Cagatay; Özenbaş, Ahmet Macit (2018-02-10) An alcohol based nickel oxide nanoparticle dispersion was prepared and used to deposit hole conductor medium for a polymeric substance free perovskite solar cell in mesoscopic n-i-p configuration. In contrast to conventional p-i-n configuration or inverted type perovskite solar cells, nickel oxide layer was spin coated directly on perovskite layer and the perovskite layer was sandwiched between two metal oxides, TiO2 and NiO, resulting in n-i-p configuration. High surface area nickel oxide nanoparticles wer...
