The voltammetric assay of Helicobacter pylori DNA was investigated using a bismuth-immobilized carbon nanotube electrode (BCNE). The analytical cyclic voltammetry (CV) peak potential was obtained at a 0.4V reduction scan, where the diagnostic optimum square-wave (SW) stripping working range was achieved at 0.72-7.92 μg/mL H. pylori DNA (11 points).

In the present study, we demonstrate the performance of Zinc oxide thin film transistors (ZnO TFTs) array subjected to the strain under high bending test and the reliability of TFTs was confirmed for the bending fatigue test of 2000 cycles. Initially, ZnO TFTs were fabricated on Si substrate and subsequently transferred on flexible PET substrate using(More)
This paper presents the notch loading effect on the pin shorted equilateral triangular shaped microstrip antenna (ETMSA). The proposed antenna shows the dual band behavior due to pin shorting and also the effect of circular notch for bandwidth enhancement, with dual shorting pin. The proposed antenna providing enhanced impedance bandwidth of 13. 42%. Also(More)
