“…Sivasankar et al (2018) introduced a new hierarchical mesoporous graphite oxide (HMGO) with Al 2 O 3 for the identification of caffeic acid in red wine samples using a modified GCE. For the detection of glycine, Alam et al Giarola et al (2017) identified that graphite-SiO 2 /Al 2 O 3 /Nb 2 O 5 -methylene blue (GRP-SiAlNb-MB) composite was suitable for the detection of dopamine, DA, in real and pharmaceutical samples with good detection limit. Other works by (Ganjali et al, 2017a;Ganjali et al, 2017b;Ganjali et al, 2018) Rakib et al (2019) and was used for the modification of GCE as a chemical sensor for sensing hazardous chemical 3,4-diaminotoluene.…”

Identifying and quantifying the biological concentrations of certain biomolecules such as dopamine, glucose, tyrosine, and cholesterol, etc. has become the basis for medical diagnosis in the treatment of a number of related diseases. In most cases, the concentrations of these biomolecules in biofluids like blood acts as a biomarker and becomes crucial in the treatment of diseases. On the other hand, advanced ceramics refers to oxides (alumina, zirconia), non-oxides: (carbides, borides, nitrides, silicides), Composites (particulate reinforced combinations of oxides and non-oxides), etc. This review article discusses recent developments in the field of electrochemical sensors developed using metal and metal oxide based advanced ceramics with an emphasis on developments in the field over the past five years. The article presents the key results, important findings, and interesting chemistry of biosensing advanced ceramic based electrochemical biosensors for some important biomolecules such as acetaminophen, glucose, and dopamine, etc.

A nonenzymatic uric acid sensor is proposed based on an electrophoretically deposited Graphene/ITO electrode (EDG). The morphology and structure of the EDGs were characterized by scanning electron microscopy (SEM) and Raman spectroscopy. As a result, the EDGs electrode was successfully fabricated with a well‐adhered graphene film on the ITO substrate surface. The electrochemical properties of the EDG for uric acid were investigated in PBS buffer pH 7.4, using cyclic voltammetry (CV) studies. Quantification of uric acid using both cyclic scanning and differential addition polarization methods. As a result, the uric acid sensor has a linear range from 1 to 100 μM, sensitivity 318.4 (μAcm2mM‐1) from CV measurements. Moreover, by the differential pulse voltammetry (DPV), the sensor has a linear range from 1 to 50 μM, a sensitivity of 1242.7 (μAcm2 mM‐1), and the detection limit (LOD) of 0.6 μM (S/N = 3). The oxidation peak potential separation of uric acid, ascorbic, and dopamine at the EDG electrode showed that the uric sensor could eliminate interferences (ascorbic acid, dopamine) and be used to simultaneously determine uric acid, ascorbic acid, and dopamine.

This study describes a fast and simple methodology for the preparation of Cerium (III) Hexacyanoferrate (II) (CeHCF) nanoparticles (NPs). The NPs were characterized by fourier transform infrared (FTIR), x‐ray diffraction (XRD), scanning electron microscopy (SEM) and cyclic voltammetry (CV). The CeHCF cyclic voltammogram indicate a well‐defined redox pair assigned as Fe2+/Fe3+ in the presence of cerium (III), with a formal potential of Eθ′=0.29 V (v=100 mV s−1, KNO3; 1.0 mol/L, pH 7.0). The carbon paste electrode modified with CeHCF (CeHCF‐CPE) was applied to the catalytic electrooxidation of dopamine applying Differential Pulse Voltammetry (DPV). DPV showed linear response at two concentration ranges, from 9.0×10−7 to 8.0×10−6 and 9.0×10−6 to 1.0×10−4 mol/L, with an LOD of 1.9×10−7 and 1.0×10−5 mol/L, respectively. The CeHCF‐CPE exhibited selectivity against substances commonly found in biological samples, with redox potentials close to that of dopamine, such as urea and ascorbic acid (AA). Subsequently the CeHCF‐CPE was successfully applied to the detection of dopamine in simulated urine samples, with recovery percentages ranging between 99 and 103%.
