Metronidazole (MTD) is a common antibiotic used to treat various pathogens and protozoal infections in humans and domestic animals. This drug is, however, prohibited in various countries owing to its extremely precarious properties. Hence, the low-limit detection of MTD in the environment is more important because it is very impactful and affects human health. Iron tungstate (Fe2WO6) has been produced by the hydrothermal method and the carbon nanofibers (CNF) prepared from the electrospinning technique. After that, CNF/Fe2WO6 composite decorated glassy carbon electrode (GCE) was used for the electrochemical detection of MTD. Here, the different physicochemical characterization studies were used to confirm the CNF/Fe2WO6 composite. Moreover, electrochemical impedance spectroscopy, cyclic voltammetry studies, and differential pulse voltammetry have been used for the electrochemical studies of modified electrodes. The electrochemical results of GCE/CNF/Fe2WO6 electrodes exhibited an excellent electrochemical response at -0.5 V. The MTD detection limit has been calculated by the very low detection limit concentrations (0.013 μM). Further, the GCE/CNF/Fe2WO6 electrodes performed at high sensitivity (1.55 μA μM−1 cm-2) with a wide linear range (0.01-1792 μM). Besides, the GCE/CNF/Fe2WO6 have excellent repeatability, reproducibility, stability, and real sample analysis performances.

This review is a critical analysis of the current state‐of‐the‐art in core spun yarn textile triboelectric nanogenerators (CSY‐T‐TENGs) for self‐powered smart sensing applications. The rapid expansion of wireless communication, flexible conductive materials, and wearable electronics over the last ten years is now demanding autonomous energy, which has created a new research space in the field of wearable T‐TENGs. Current research is exploring T‐TENGs made from CSYs as stable and reliable energy harvesters and sensing devices for modern wearable IoT platforms. CSY‐TENGs are emerging as an important technology due to its simple structure, low cost, and excellent performance in converting mechanical energy into electrical energy and due to its sensing ability. This paper provides a critical review on current progress, it analyzes the unique advantages of CSYs T‐TENGs over conventional T‐TENGs, it describes fabrication techniques and discusses the materials used along with their properties and electrical performance characteristics, and it highlights the recent advancements in their integration with self‐excitation circuits, charge storage devices and IoT‐enabled smart sensing applications, such as environmental and health monitoring. In the conclusion, it discusses the challenges and future directions of CSYs T‐TENGs and it provides a future road map for optimization, upscaling, and commercialization of the technology.

“…Metal sulfides are a series materials with low cost, excellent electrocatalytic activity and fast electron transfer property [141]. The modification of metal sulfides on graphene is often achieved through the hydrothermal chemical synthesis by adding different sulfur sources into the solutions containing metal ions and graphene [128b–e]. The oxygen‐containing groups on GO or rGO can offer the numerous binding sites for the functionalization of metal sulfides with uniform size and dispersion.…”

Graphene, a honeycomb lattice of carbon material with single‐atom‐layer structure, demonstrates extraordinary mechanical, thermal, chemical and electronic properties. Thus, it has sparked tremendous interests in various fields, such as energy storage and conversion devices, field‐effect transistors (FET), chemical sensors and biosensors. In this review, we will first focus on the synthesis method of graphene and the fabrication strategy of graphene‐based materials. Subsequently, the construction of graphene‐based biosensors are introduced, in which three kinds of biosensors are discussed in details, including the FET, electrochemical biosensors and electrochemiluminescence (ECL) biosensors. The performances of the state‐of‐the‐art biosensors on the detection of biomolecules are also displayed. Finally, we also highlight some critical challenges remain to be solved and the development in this field for further research.
