摘要: Abstract In this study, a new approach for glucose sensing emphasizing on cost-effectivity and simplicity while sensitivity of sensor remains high enough, is proposed. respect, we prepared CuO nanodisks having an ellipsoidal form without using any template or surfactants just by microwave irradiation 5 min used it to modify disposable commercial screen printed carbon electrodes(SPCE) kind binders like nafion. The synthesized nanostructure has been thoroughly characterized various complementary techniques (SEM, TEM, FT-IR, XRD) the performance proposed electrochemical was investigated as sensing. Different effective parameters sensor, including KOH concentration, applied potential, repeatability, stability selectivity, were discussed. linear dynamic range, from 2.0 μM 2.5 mM, with detection limit 0.2 μM (at signal noise ratio 3) 627.3 μA mM−1 cm−2, are comparable better than many more sophisticated sensors. Therefore, simple sensitive can offer cost-effective high-performance respect previously reported copper oxide based Capability measurement evaluated in human urine sample.
