- * Researchers utilized a hydrothermal synthesis method to create layer-like structured vanadium sulfide (VS) as an electrode modification material for an electrochemical sensor targeting SMX detection.
- * The VS electrodes achieved a detection limit of 47.0 nM and demonstrated good recovery rates in practical tests, confirming their accuracy and potential for sensitive detection of SMX in natural waters.
Bisphenol A (BPA) is an industrial chemical used extensively in plastics and resins. However, its endocrine-disrupting properties pose risks to human health and the environment. Thus, accurate and rapid detection of BPA is crucial for exposure monitoring and risk mitigation.

In this work, a novel electrochemical aptasensor based on polyethyleneimine grafted reduced graphene oxide and titanium dioxide (rGO/PEI/TiO) nanocomposite was constructed for ultrasensitive and selective detection of CIP. Through the in-situ electrochemical oxidation of TiCT nanosheets, TiO nanosheets with good electrochemical response were prepared in a more convenient and eco-friendly method.

- - A sensitive electrochemical sensor for dopamine (DA) was created by using gold nanoparticles on marimo-like graphene, which enhances the sensor's performance when attached to a glassy carbon electrode (GCE).
- - Marimo-like graphene (MG) was produced through the partial exfoliation of mesocarbon microbeads, resulting in a structure with multi-layer graphene nanowalls that increases surface area and electroactive sites for better detection.
- - The developed sensor showed significant electrochemical activity and a detection range for DA from 0.02 to 10 μM, with a low detection limit of 0.016 μM, proving effective against potential interference from uric acid in real samples.
