“…Based on the experimental results, the improved sensor can be used to monitor glucose levels in biological fluids for real clinical care site tests. Maity et al ( 2019 ) established a highly sensitive glucose biosensor by using an amine terminated MWCNTs/polyaniline/reduced graphene oxide/gold nanoparticles to modify screen-printed carbon electrode followed by linking glucose oxidase on the surface of electrode. Wang et al ( 2019 ) developed a new nanomaterial by meso-cellular silicate and foam reduced graphene oxide to detect glucose, which exhibited good analytical performance for the detection of glucose.…”

Metabolic diseases have become common diseases with the improvement of living standards because of changed dietary habits and living habits, which seriously affect health. Currently, related biomarkers have been widely used as important indicators for clinical diagnosis, treatment, and prognosis of metabolic diseases. Among all detection methods for biomarkers of metabolic diseases, electrochemical sensor technology has the advantages of simplicity, real-time analysis, and low cost. Carbon nanomaterials were preeminent materials for fabricating electrochemical sensors in order to enhance the performance. In this paper, we summarize the research progress in the past 3 years of electrochemical sensors based on carbon nanomaterials in detecting markers of metabolic diseases, which include carbon nanotubes, graphene, carbon quantum dots, fullerene, and carbon nitride. Additionally, we discuss the future prospects for this field.

Cadmium (Cd) is a heavy metal that has high toxicity. Cadmium levels need to be considered in an environment that can accumulate and can poison all biotic components. In this research measurements of cadmium metal using bismuth-modified carbon screen electrode used cyclic voltammetry method. The parameters considered are the resolution of the comparative electrodes and the voltage produced from variations in cadmium concentration. The test results prove the stability of three sensors each at a voltage of 3.3 - 4.6 mV, 9.3-11.4 mV, and 27.4 - 29.8 mV. While the results of the cyclic voltammetry characterization test vary depending on the concentration of cadmium. Concentrations of 0.5-100 ng / mL produce an oxidation peak at a current of 2.03 x 10-5 - 5.00 x 10-5 A. These results show a directly proportional relationship between the cadmium concentration and the resulting current.

“…Biosensors with high selectivity, sensitivity, and time resolution can be constructed by combining electrochemical analysis with enzyme reactions. Electroactive compounds, such as H 2 O 2 [4,5] or NADH [6,7], generated by enzymatic reactions can be detected by electrochemical analysis. Glucose oxidase, which generates H 2 O 2 from glucose and O 2 , has been used in blood glucose sensors for diabetes.…”

“…Glucose oxidase, which generates H 2 O 2 from glucose and O 2 , has been used in blood glucose sensors for diabetes. The blood glucose level is measured from the anodic current of H 2 O 2 [4,5]. However, these H 2 O 2 biosensors have the drawbacks of requiring a platinum electrode and having a high electrode potential of about + 0.6 V (vs. Ag/AgCl) for the electrochemical oxidation of H 2 O 2 .…”

Enhancement of Hydrogen Peroxide Reduction Current by an Electrode Modified with Hybrid Polymer/Silica Particles and N,N‐diethyl‐N‐(2‐methoxy‐ethyl)‐N‐methylammonium bis(trifluoromethylsulfonyl)imide

The electrochemical reaction of H 2 O 2 was promoted by an electrode modified with N,N-diethyl-N-(2-methoxy-ethyl)-N-methylammonium bis(trifluoromethylsulfonyl)imide (DEME-TFSI) and hybrid polymer/silica particles, which consisted of an ionic liquid-type polymer brush decorated with silica particles (PSiP). The electrode was prepared by dropping an acetonitrile solution of homogeneously dispersed PSiPs and DEME-TFSI on a glassy carbon (GC) electrode and drying. During cyclic voltammetry in the presence of 3.0 mM H 2 O 2 , the reduction current at À 0.400 mV increased from 0.9 to 3.3 μA compared with the unmodified GC electrode, demonstrating that the electrochemical reduction of H 2 O 2 was promoted on the PSiP/DEME-TFSI-modified electrode.
