In this work, UiO-66-NH2/GO nanocomposite was prepared using a simple solvothermal technique, and its structure morphology were characterized field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), diffraction (XRD). An enhanced electrochemical sensor for the detection of epirubicin (EP) proposed, which utilized nanocomposite-modified screen-printed graphite electrode (UiO-66-NH2/GO/SPGE). The improved performance SPGE towards redox reaction EP. Under optimized experimental conditions, demonstrates remarkable limit (LOD) 0.003 µM linear dynamic range from 0.008 to 200.0 µM, providing highly capable platform sensing Furthermore, simultaneous electro-catalytic oxidation EP topotecan (TP) investigated at UiO-66-NH2/GO/SPGE surface utilizing differential pulse voltammetry (DPV). DPV measurements revealed presence two distinct peaks TP, with peak potential separation 200 mV. Finally, successfully quantitative analysis TP in pharmaceutical injection, yielding satisfactory results.

The manuscript provides a comprehensive study of the design and utilization graphene-based prototypes designed to detect catechol molecules. Graphene has been one pioneering nanomaterials in current era due its exceptional electromechanical thermal characteristics. Because remarkable aspect ratio charge carrier properties, it used various physicochemical forms develop electrodes for electrochemical sensing applications. Catechol represents toxic organic compounds that is present naturally occurring fruits vegetables. Exposure catechol, even small amounts, causes disastrous nerve-related issues. This paper underscores research conducted on detecting molecules using certain graphene allotropes like bare graphene, oxide, reduced oxide. also mixed with other processing materials form polymers pure nanocomposite sensors. Each these robust efficient regards their linear range, sensitivity, operating values, response time. last part elucidates challenges proposes potential remedies.

In the present work, CeO2 nanoparticles (CeO2 NPs) were prepared by hydrothermal method and crystal structure morphology analysis studied using a series of characterizations. Then, screen-printed carbon electrode (SPCE) modified with NPs was employed to develop simple novel sensor for sulfite determination in water samples. The NPs/SPCE showed significant current response oxidation. use developed differential pulse voltammetry (DPV) provides wide linear range (0.08 870.0 µM) low limit detection (LOD) (0.023 µM). Finally, results samples good recoveries between 96.7-102.7% relative standard deviation (RSD) less than 3.6%.

Considering the increasing concern for food safety, electrochemical methods detecting specific ingredients in are currently most efficient method due to their low cost, fast response signal, high sensitivity, and ease of use. The detection efficiency sensors is determined by electrode materials’ characteristics. Among them, three-dimensional (3D) electrodes have unique advantages electronic transfer, adsorption capacity exposure active sites energy storage, novel materials, sensing. Therefore, this review begins outlining benefits drawbacks 3D compared other materials before going into more detail about how synthesized. Next, different types outlined together with common modification techniques enhancing performance. After this, a demonstration safety applications, such as components, additives, emerging pollutants, bacteria food, was given. Finally, improvement measures development directions discussed. We think that will help creation new offer fresh perspectives on achieve extremely sensitive area safety.
