“…Recently, different methods can be used for the detection of diabetes such as high-performance liquid chromatography (HPLC), boronate affinity chromatography, thiobarbituric acid (TBA), and ion exchange chromatography. − Although these methods are producing sensitive results, they also have various drawbacks like expensive instruments and infrastructure, smaller storage periods, and long processing time, with a complex and time-consuming sample preparation process. − Therefore, new technology and methods are needed to be introduced for removing these constraints, and a promising solution to this problem can be the use of biosensors. − Therefore, in this study, an electrochemical nanobiosensor was introduced. The biosensor is designed to identify the level of glycated hemoglobin (HbA1c) in diabetic patients.…”

Diabetes is a global menace, and its severity results in various disorders including cardiovascular, retinopathy, neuropathy, and nephropathy. Recently, diabetic conditions are diagnosed through the level of glycated hemoglobin. The level of glycated hemoglobin is determined with enzymatic methodology. Although the system is sensitive, it has various restrictions such as long processing times, expensive equipment required for testing, and complex steps involved in sample preparation. These limitations are a hindrance to faster results. The limitations of the developed methods can be eliminated through biosensors. In this work, an electrochemical platform was fabricated that facilitates the identification of glycated hemoglobin protein in diabetic patients. The working electrode on the integrated circuit was modified with molecularly imprinted polymer decorated with tungsten disulfide nanoparticles to enhance its analytical properties. The analytical properties of the biosensor were studied using electrochemical techniques. The obtained detection limit of the nanoelectronic sensor was 0.01 pM. The calculated sensitivity of the biosensor was observed to be 0.27 μA/pM. Also, the sensor promises to operate in a dynamic working concentration range and provide instant results.

“…The chemical modification of inert substrate electrodes offers significant advantages in the design and development of electrochemical sensors [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. A further advantage of chemically modified electrodes is that they are less prone to surface fouling and oxide formation compared to inert substrate electrodes [27][28][29][30][31][32][33][34][35][36][37][38][39].…”

A novel MnO2 nanorods modified screen-printed electrode was fabricated and used as a voltammetric sensor for Sudan determination. MnO2 nanorods were characterized using Field emission-scanning electron microscopy (FE-SEM). Electrochemical measurements were performed using cyclic voltammetry (CV), linear sweep voltammetry (LSV), differential pulse voltammetry (DPV), and chronoammperometry (CA). The MnO2 nanorods on the electrode surface act as an excellent catalyst for the Sudan oxidation reaction. Our modified electrode presents good electrocatalytic activity toward Sudan, a short response time of <10 s, a low detection limit of around 0.08 µM, and linear detection range from 0.25 to 300.0 µM.

The electrochemical sensors for carmoisine detection were explored and applied in the field of food safety because of the striking merits of fast detection speed, high sensitivity and easy operation. Herein, we developed a high-performance electrochemical carmoisine sensor based on g-C3N4 and ionic liquids (ILs), prepared by a one-pot hydrothermal synthesis method. Most importantly, the sensing performances of electrochemical carmoisine sensors based on g-C3N4 (graphitic carbon nitride)/IL (1-butyl-3-methylimidazolium hexafluorophosphate) are better than the bare carbon paste electrode (CPE) sensors. The detection limit of this sensor (g-C3N4/ILs/CPE) determined via differential pulse voltammetry was 0.1 µM over a wide linear range of 0.4–125.0 µM.
