“…Next, the performances of the resulted glucose electrochemical sensor were compared with other nonenzymatic sensors ,,,. As shown in Table , the linear range of 3D‐KSC/CuO@carbon /AuNPs integrated electrode was much wider than that of PVA/MnO 2 @GO/CuO electrode (0.5‐4.4 mM) and SiO 2 /C/CuO electrode (0.02‐20 mM) .…”

The detection limit was also far lower than that of CuO‐CS/GCE electrode (11 μM) and CuONWAs/CW‐500 (2.86 μM) . At the same time, the resulted sensor also had a higher sensitivity than NPG/CuO electrode (374 μA mM −1 cm −2 ) and NGA‐CuO electrode (233.1 μA mM −1 cm −2 ) .…”

A novel nonenzymatic glucose sensor based on CuO@Carbon nanostructures capped with gold nanoparticles (AuNPs) arrayed on three‐dimensional porous carbon derived from kenaf stem (3D‐KSC) was proposed. Here, the massive 3D‐KSC with honeycomb‐like structure was used as supporting matrix to load CuO@Carbon nanostructures. A small amount of AuNPs were coated on CuO@Carbon nanostructures, which were arrayed on 3D‐KSC uniformly. The AuNPs improved the electrical conductivity and catalytic activity of CuO@Carbon nanostructures greatly. Thus, the 3D‐KSC/CuO@Carbon/AuNPs integrated electrode based nonenzymatic glucose sensor showed good performance with the linear range of 3.71 μM–8.5 mM, the detection limit of 1.22 μM and the sensitivity of 935 μA cm−2 mM−1. The satisfied performance made sure it can be used to detect glucose in real blood samples.

“…However, the literature revealed that the hybridization of Copper with chitosan reduces the toxicity level [14]. Also it was repoted that nano Cu and CuO are considered as effective antibacterial agents [14][15] [16], According to the literature, chemical reduction method is a facile process for the synthesis of NP's using biopolymeric materials [17] in achieving a better substantial bacteriostatic/bactericidal property.…”

Novel synthesized Chitosan-Copper oxide nanocomposite (Cs-CuO) was prepared using pomegranate peels extract as green precipitating agents to improve the biological activity of Cs-NP's which was synthesized through ionic gelation method. The characterization of biogenic nanoparticles Cs-NP's and Cs-CuO-NP's were investigated structurally, morphologically to determine the full descriptive features of those nanoparticles. Antimicrobial activity was tested for both Cs-NP's and Cs-CuO-NP's via Minimum inhibition concentration and zone analysis against fungus, gram positive and gram negative. The results of the antimicrobial test showed high sensitivity of Cs-CuO-NP's to all microorganisms that are tested in concentration less than 20 mg/ml while the sensitivity of Cs-NP's against all microorganisms under test started from a concentration of 20 mg/ml to 40 mg/ml except for the C.albicans species. Hematological activity was also tested in via measuring the RBCs, platelets count and clotting time against healthy, diabetic and hypercholesterolic blood samples. Measurement showed a decrease in RBCs and platelets count by adding Cs-NP’s or Cs-CuO-NP's to the three blood samples. Cs-NP’s success to decrease the clotting time for healthy and diabetic blood acting as a procoagulant agent, while adding biogenic CuO-NP’s to Cs-NP’s increased clotting time considering as an anticoagulant agent for hyperchloesterolic blood samples.

We report on the synthesis of copper (II) oxide (CuO)/indium tin oxide (ITO) electrode via the electrochemical deposition method using a CuSO4 solution and then thermal oxidation in air at temperature of 400 oC for 2 h. The crystalline structure and morphology of CuO were characterized by scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). The electrochemical properties of the CuO/ITO electrode to glucose in the alkaline medium of 0.1 M NaOH solution were investigated by cyclic voltammetry (CV) and Chronnoamperometry. The CuO-N/ITO electrode showed the best electrochemical properties for glucose detection in comparison to the others. Chronnoamperometry of CuO-N/ITO electrode to the glucose response showed excellent stability, the linear range of 1 mM to 3600 mM with high sensitivity of 283.6 mAcm-2mM-1 and 0.61 mM of the detection limit (S/N=3). A good response of the CuO-N/ITO electrode, which was investigated for different human serum samples, indicates a high potential of its towards a glucose sensor for analysis in real examples.
