“…However, nitrofurazone drug residues may enter the ecosystem, food chain, and drinking water. Long-term intake of this antibiotic can lead to liver disease, lung fibrosis, carcinogenicity, and birth defects [1,2]. Because of its dangers, the use of this antibiotic is prohibited for both people and animals in many nations, including the European Union.…”

Metal–organic frame (MOF) materials may have the advantages of a regular pore structure, large porosity, and large specific surface area, which could provide better catalytic activity, but they have some disadvantages in electrocatalysis. In contrast, carbon nanofibers (CNFs) prepared by electrospinning methods have good conductivity and stability. Therefore, this research aimed to generate MOF/CNFs composite materials to improve the electrochemical properties of MOF materials and apply them to the field of electrochemical sensing. This experiment was based on the preparation of straight unidirectional CNFs by an electrospinning method at 2000 RPM. The original method of preparing zeolitic imidazolate frameworks (ZIF-8) was improved and ZIF-8 was uniformly dispersed on the surface of CNFs to form a ZIF-8/CNF composite with a fiber diameter of about 0.10 to 0.35 µm. The specific surface area of the CNFs was about 42.28 m2/g, while that of the ZIF-8/CNF composite was about 999.82 m2/g. The specific surface area of the ZIF-8/CNF composite was significantly larger than that of CNFs. The GCE/ZIF-8/CNF electrode had an excellent electrochemical reaction, with an oxidation peak at about 216 μA, which proved that the ZIF-8/CNF composite material would have good catalytic activity and excellent electrochemical properties for the detection of nitrofurazone compared to other modified electrodes.

“…10 Taking this situation into account, there is an urgent need to develop various analytical methods with high sensitivity to detect the trace concentration of NFZ. However, the developed methods, including electrochemical sensing, 6,11,12 flow injection chemiluminescence, 13 liquid chromatography-mass spectrometry, and high performance liquid chromatography, 14,15 have some limitations in insufficient sensitivity, slow response, high cost, and tedious sample preparation. Surface-enhanced Raman spectroscopy (SERS) is an ultrasensitive analytical technique with the features of providing molecular vibration fingerprint information, short measurement time, and non-destructive detection.…”

The construction of noble-metal incorporated semiconductor hybrids for the detection of antibiotics has intrigued great interest among researchers in the field of surface-enhanced Raman spectroscopy (SERS). However, the production of SERS substrates to accomplish the effective enhancement of the Raman signal was a bottleneck to researchers for the past decades. This study investigates the SERS performance of anisotropic Ag nanoprisms (Ag NPrs) attached onto the surface of Cu2O microspheres for the trace-level antibiotic detection of nitrofurazone (NFZ). Physicochemical activities and surface morphologies of the prepared hybrids were meticulously examined using various analytical techniques. The eminent sharp tips and edges of Ag NPrs deposited on Cu2O microspheres endow enormous intensity enhancement of the Raman signal of NFZ in the innumerable hotspot regions through the synergistic utilization of electromagnetic enhancement and charge transfer enhancement. The proposed hybrid-based SERS substrate provides superior detection performance, including high sensitivity, high enhancement factor of 2.31 × 1011, ultra-low limit of detection of 5.80 × 10–13 M, superior spot-to-spot uniformity, and substrate-to-substrate reproducibility <8.31% for NFZ detection. Furthermore, the real-sample analysis performed on NFZ in local pond water shows satisfactory recovery values from 81 to 96%. The presented sensing characteristics demonstrate that the proposed Ag-NPrs/Cu2O-based SERS substrate possesses promising features for detecting NFZ in standard and real-sample applications.

In this work, the Tb2(WO4)3/C3N4 composite is for the electrochemical sensing of 4‐nitrophenol (4‐NP). Tb2(WO4)3 was prepared by hydrothermal method. Tb2(WO4)3 homogeneously functionalized with the g‐C3N4 by a noncovalent π–π interaction. Besides, field emission scanning electron microscopy, x‐ray diffraction studies, and energy‐dispersive x‐ray spectroscopy were utilized to characterize the prepared materials. Cyclic voltammetry and amperometry techniques were used to investigate the electrocatalytic behavior of prepared electrode materials. The reduction in 4‐NP exhibits high electrocatalytic activity, with best at working voltage with a linear response range of up to 1200 μM. Moreover, the SPCE/C3N4/Tb2(WO4)3 electrode exhibited a detection limit and sensitivity of 0.23 μM and 1.72 μAμM−1 cm−2, respectively. The electrode provides a workable platform for the analysis of 4‐NP in water samples and is highly reproducible and stable.
