“…Thus, it was vital to focus on improving the catalytic efficiency. Research findings have shown that trivalent lanthanide ions such as Eu 3+ , Nd 3+ , and others, can effectively facilitate the generation of free radicals during photocatalysis. , Therefore, to investigate the improvement in the H 2 O 2 catalytic reaction efficiency of this novel system, we tried to introduce trivalent lanthanide ions (Te 3+ , La 3+ , Eu 3+ , Nd 3+ ) into the C-FeO@Mn-based detection system. A noteworthy boost in signal intensity at 652 nm was observed in the reaction systems containing Nd 3+ and Eu 3+ (Figure A).…”

The iron nanozyme-based colorimetric method, which is widely applied for biosubstrate detection in in vitro diagnosis (IVD), faces some limitations. The optimal catalytic conditions of iron nanozymes necessitate a strong acidic environment, high temperature, and other restrictive factors; additionally, the colorimetric results are highly influenced by optical interferences. To address these challenges, iron nanozymes doped with various transition elements were efficiently prepared in this study, and notably, the manganese-modified one displayed a high catalytic activity owing to its electron transfer property. Furthermore, the introduction of lanthanide ions into the catalytic reactions, specifically the neodymium ion, significantly boosted the generation efficiency of hydroxyl radicals; importantly, this enhancement extended to a wide range of pH levels and temperatures, amplifying the detection signal. Moreover, the nanozyme's superparamagnetic characteristic was also employed to perform a logical optical and magnetic resonance dual-modality detection for substrates, effectively eliminating background optical interference and ensuring a reliable verification of the signal's authenticity. Based on this magnetic signal, the integration of natural glucose oxidase with the nanozyme resulted in a notable 61.5% increase in detection sensitivity, surpassing the capabilities of the traditional colorimetric approach. Consequently, the incorporation of lanthanide ions into the magnetic nanozyme enables the effective identification of physiological biomarkers through the dual-modality signal. This not only guarantees enhanced sensitivity but also demonstrates significant potential for future applications.

“…Nitrofurazone (NFZ) is a synthetic nitrofuran antibiotic, which is widely used in the prevention and treatment of aquatic animal diseases [1]. Effective antibacterial activity against susceptible anaerobic infections [3]; It can impede the sugar metabolism of microorganisms and inhibit the growth process of protein synthesis; it is effective against a wide range of Gram-negative and Gram-positive bacteria. More importantly, nitrofurazone can be used to treat suppurative otitis media and dermatitis, acute and chronic rhinitis, burns, and ulcers [4].…”

An electrochemical sensor for the rapid detection of nitrofurazone in aquaculture seawater using a glassy carbon electrode (GCE) modified with Au nanoparticles (AuNPs) was constructed. Compared with the unmodified electrode, the modified electrode had higher electrocatalytic activity than the GCE and could be used for the detection of nitrofurazone efficiently. It could be found that the AuNPs modified electrode had higher specific surface area by the characterization of scanning electron microscopy. The effects of parameters such as electro-polymerization cycles for modified electrode preparation, the pH of the electrolyte for the detection of nitrofurazone were optimized. Under optimized experimental conditions, the peak current and concentration of nitrofurazone varied linearly in the range of 3 µM to 100 µM under square wave voltammetry (SWV), with the limit of detection of 0.24µM. The proposed sensor was successfully applied for the detection of nitrofurazone in aquaculture seawater, and the spiked recoveries were 96.35%-107% (RSD<4.13%), which indicated that the method has satisfactory accuracy and performance for the detection of nitrofurazone in real seawater.
