Pt Dendrite Oxide Probe에 코팅된 전도성 고분자를 기반으로 한 pH & Glucose 센서 제작

Abstract

We report pH and glucose sensors using the conducting polymer coated-Pt dendrite oxide probe. Scanning Electron Microscopy (SEM) and X-ray photoelectron Spectroscopy (XPS) were employed to characterize the structural and morphological features of electrodeposited dendrite layer. The conductive polymer pH sensor was worked in the range of pH 3~13. The calibration plots exhibited a Nernst behavior (slope:-59.2mV/pH) in the buffer solution. Additionally, the potentiometric analysis of glucose through monitoring pH change was performed, which was enzymatically generated on the sensor at the range from 0.5mM to 10mM with a sensitivity of 6.138±0.4348mV/mM. In real blood sample analysis, the glucose concentration in human blood was found to be 4.901±0.6338
