The sensing properties of Au-EGFET with body effect for DNA detection were first investigated in this study. The body effect means different substrate bias in CMOS circuit operation without common ground. With positive VBS of 1V, more shift of ID-VG curve could be a good index of DNA hybridization and concentration. It could be explained be the electric field induced counter ion effect. This measured...
In this study, the ammoniated indium tin oxide (ITO) films prepared by different condition of NH3 plasma treatment on flexible polyethylene terephthalate substrates are proposed as sensing electrodes of extended-gate field-effect transistors (EGFETs). pH sensitivity calculated from the output voltage in buffer solution from pH 2.1 to pH 12.1 in the samples with NH3 plasma treatment for 6min is slightly...
