Designing effective and accurate methods to determine bisphenol A (BPA) residues is crucial for safeguarding food safety preserving the environment. The main objective of present work develop a simple sensitive electrochemical sensor detect BPA based on modified carbon paste electrode (CPE). For this, CeO2 nanoparticles (CeO2 NPs) ionic liquid (IL) were used modify CPE. Cyclic voltammetry (CV) was utilised as technique investigate behaviour at surface various electrodes (unmodified CPE, NPs/CPE, ILCPE, NPs/ILCPE). obtained result showed that NPs/ILCPE exhibited better electrocatalytic performance oxidation than observed other CPEs. quantification BPA, differential pulse (DPV) utilised. Under optimum detection conditions, good linearity in within range 0.02–460.0 µM with limit (LOD) 0.01 µM. Finally, enhanced response from NPs/IL-modified CPE towards has been evaluate practical application this sensor. results (recovery relative standard deviation (RSD) values) confirmed applicability real samples. Based findings, appears be suitable platform determination.

Bisphenol A (BPA) is a typical environmental estrogen that distributed worldwide and has the potential to pose hazard ecological environment human health. The development of an efficient sensitive sensing strategy for monitoring BPA residues paramount importance. novel electrochemical sensor based on carbon black nanofibers composite (CB/f-CNF)-assisted signal amplification been successfully constructed amperometric detection in foods. Herein, hybrid CB/f-CNF was prepared using simple one-step ultrasonication method, exhibited good electron transfer capability excellent catalytic properties, which can be attributed large surface area strong enhancement conductivity porosity nanofibers, promote faster process electrode surface. Under optimized conditions, proposed CB/f-CNF/GCE wide linear response range (0.4–50.0 × 10−6 mol/L) with low limit 5.9 10−8 mol/L quantification. Recovery tests were conducted canned peaches boxed milk, yielding satisfactory recoveries 86.0–102.6%. Furthermore, developed method employed rapid meat packaged demonstrating comparable accuracy HPLC method. This work presents through utilization carbon/carbon nanocomposite sensitization technology.

Food safety is a key issue in promoting human health and sustaining life. analysis essential to prevent food components or contaminants causing foodborne-related illnesses consumers. Electrochemical sensors have become desirable method for due their simple, accurate rapid response. The low sensitivity poor selectivity of electrochemical working complex sample matrices can be overcome by coupling them with covalent organic frameworks (COFs). COFs are kind novel porous polymer formed light elements, such as C, H, N B, via bonds. This review focuses on the recent progress COF-based analysis. Firstly, synthesis methods summarized. Then, discussion strategies given improve electrochemistry performance COFs. There follows summary recently developed determination contaminants, including bisphenols, antibiotics, pesticides, heavy metal ions, fungal toxin bacterium. Finally, challenges future directions this field discussed.

In this work, a sensitive sensing platform was developed using glassy carbon electrode (GCE) to simultaneously determine AA, DA, and UA. Cu nanostructures, the poly-L-Lysine ( p (L-Lys)), electrochemically reduced graphene oxide (ERGO) modified GCE (GCE/Cu@ERGO- (L-Lys)) via electrodeposition of electropolymerization ERGO- (L-Lys). Simultaneous detection makes analysis more efficient cost-effective by reducing need for multiple sensors. The GCE/Cu@ERGO- (L-Lys) characterized electrochemical impedance spectroscopy, cyclic voltammetry, scanning electron microscopy. limit values UA analytes were 0.16, 0.033, 0.021 μ M, respectively, while linear ranges 0.53–50.0, 0.11–100.0, 0.070–0.75 M. proposed sensor found be applicable determination target in fetal bovine serum samples. hybrid composite is promising material simultaneous biological fluids with excellent analytical performance anti-interference effect.
