제목 Enzyme biosensor based on N-doped carbon nanotube electrode prepared by thermal solid-state reaction of modified CNT and urea
초록 The N-doped carbon nanotube for an enzyme-based glucose sensor was prepared by reaction of modified CNT and urea. The CNT was modified by H2SO4 for introducing oxygen functional groups which were reacted with urea. The reactions were carried out various weight ratios of amounts of urea per modified CNT (0.5:1, 1:1, 3:1, 5:1) and temperature (200-600 OC). The synthesized samples were characterized by X-ray photoelectron spectroscopy to analysis chemical elements composition on the surface. Glucose sensing was carried out by current voltagram and amperometric methods. The mechanism of the sensitive on enzyme activity in the electrodes of glucose sensor was modeled by enzyme kinetics using the Michaelis-Menten equation.
