“…Currently, several low-cost transition metal oxides such as Fe 2 O 3 , [26][27] Mn x O x , [6,28] MoO 2 , [29] CdO, [30] NiO, [1][2][31][32] ZnO, [33] and CuO [25,[34][35][36][37] have been studied for use in non-enzymatic glucose sensors. Among all of these metal oxides, CuO has been widely explored as a catalytic material for different applications including semiconductors, supercapacitors, batteries, solar energy conversion, gas sensing devices, catalysis, biosensors, and transistors because it is a p-type semiconductor with a band gap of 1.2 eV, and it exhibits a low overpotential for electron exchange, excellent electrocatalytic activity, high active surface area, good chemical stability, and biocompatibility.…”

A simple and environmentally‐friendly approach was developed to synthesize 2D CuO nanosheets using electrochemical deposition. The formed 2D CuO nanosheets (NSs) exhibit numerous advantageous properties such as no toxicity, high electrical conductivity, large active surface area, and a p‐type semiconducting nature with a band gap of 1.2 eV. A sensitive electrochemical sensor was constructed for the amperometric detection of glucose to take advantage of these characteristics. The fabricated sensor displayed an excellent sensitivity of 2710 μA mM−1 cm−2 along with a wide linear range of 0.001–1.0 mM and a lower limit of detection of 0.8 μM (S/N=3). Additionally, the modified electrode possesses high selectivity and good stability. The outstanding electrocatalytic performance of the electrode is attributed to a large active surface area, unique structural morphology, and the high conductivity of the 2D CuO nanosheets.

In the present study, the facile and synergistic approach for electrochemical sensing of paracetamol (PA) drug was demonstrated by hydrothermally synthesized copper oxide-copper ferrite nanohybrid composite supported on reduced graphene oxide (CuO-CuFe2O4@rGO) glassy carbon electrode. The surface texture and structural information of the electrode material were examined by FE-SEM, HR-TEM, and X-ray diffraction techniques, whereas the electrochemical sensing application of paracetamol oxidation was investigated by cyclic voltametry method. The average crystallite size of CuO-CuFe2O4 was calculated from XRD data and found to be 35.45 nm. The fabricated sensor exhibited a higher sensitivity of 970.26 µA.mM-1.cm-2along with a lower limit of detection (LOD) and limit of quantification (LOQ) of 7.0 µM and 25 µM, respectively, with a linear dynamic range of 10 - 1200 µM. Furthermore, the CuO-CuFe2O4@rGO modified sensor showed excellent anti-interferents ability, long-term stability and reproducibility towards electro-oxidation of paracetamol drug. Moreover, it can be efficiently applied for the analysis of paracetamol in biological samples. Finally, the synthesized nanocomposite material was validated to be a competent electro-catalyst for electrochemical sensing application of paracetamol.
