Biosensing studies on CuO-MgO nanocomposites for glucose detection

Approximately 3 million people around the world suffer from diabetes. One of the basic indications of an individual suffering from diabetes can be observed in the form of peaked levels of glucose in the blood. Thus, it is imperative for a non-invasive mechanism to be derived through which glucose levels in the blood can be detected throughout a regular time frame. The aim of this project focuses on synthesis of a nanocomposite which can be used to detect glucose levels in the blood in a non-invasive manner. The selected nanocomposite was made from a mixture of CuO and MgO. Once synthesized, it was subjected to a series of tests and scans. The results demonstrated effective and efficient glucose detection activity of the CuO-MgO nanocomposite

Non-invasive Electrochemical Detection of Glucose using CuO-NiO/MXene Modified Electrode

High levels of glucose or acetone in breath confirms diabetes disease. One of the analytical devices that detect changes in breath is the electrochemical sensor having high selectivity, easy to use and being able to meet diabetic patient's needs. In this study sensors were made by fabricating metal oxide coated glassy carbon electrodes and using nafion as a proton conductor. Characterization methods such as X-ray diffraction, FTIR and morphological analysis have been performed for metal oxides to characterize their atomic arrangement and composition. Also, electrochemical studies were done using Gamry instrument and curves plotted as current in amperes versus voltage to test the coated electrodes conductivity. High selectivity sensors provide promising applications in any field

Detection of acetone in breath solution using nanocomposite CeO2-NiO-ZnO

Acetone level of diabetic patients from their breath can be detected. The effect of CeO2 -NiO-ZnO nanocomposite was studied by adding different concentration of acetone. Structural (XRD, Raman) and morphological (SEM with EDAX) studied were done. The CV response of modified GCE with and without acetone was studied. It was observed that the current gets reduced in the presence of acetone. The sensor shows excellent sensitivity, selectivity and durability. The flexibility is an additional advantage of the sensor

Synthesis, characterization and biosensor applications of CuO-NiO nanocomposite

The effect of CuO-NiO nanocomposite was studied by addition of various concentrations of acetone. High acetone level in human breath is an indication of the diabetes. Studies were performed to determine the structure (XRD, Raman) and morphology (SEM with EDAX). The CV response of modified GCE with and without acetone was studied. It was observed that in the presence of acetone there is a reduction in current. These sensors show excellent flexibility and can used to fabricate the sensors to stick on the body

Construction of Modified CuO-Co3O4-ZnO Electrode for Acetone Detection in Breath

Acetone in breath can be used as a biomarker for noninvasive detection of diabetes. The acetone level in breath is substantially high for diabetic patients. In this study, mixed metal oxide nanocomposite of CuO-Co3O4 -ZnO was used for the electrochemical detection of acetone in artificial breath solution. The structural and morphological characterization of synthesized nanocomposite was done by XRD, RAMAN and SEM (EDAX) analysis. The electrochemical study was performed and the metal oxide modified electrode showed the sensitivity of 6.52 ?A cm-2 ppm-1 towards the detection of acetone in the artificial solution
