“…However, these conventional methods have specific bottlenecks; are costly and tedious; and require several preprocesses, sophisticated instrumentation, complex sample preparation methods, and consumption of hazardous organic solvents. On the other hand, electrochemical sensors truly address these shortcomings because they are highly sensitive and cost-effective; consume less time; require fewer processing steps; and offer robust analysis, reproducibility, and selectivity. − …”

Bisphenol A (BPA) is broadly used in the plastic industry and has several health effects, especially on the brain and prostate gland of fetuses. BPA is a major environmental pollutant that drains into bodies of water and leaches from food packaging. Since it is a known endocrine disruptor, its extensive release into the environment is a serious concern. Thus, regular monitoring of BPA through a reliable and sensitive method is a strategy that can help alleviate its impact. To tackle this issue, an excellent conductive material based on a NiO/ZnO/rGO nanohybrid was used as an electrocatalyst to determine BPA in drinking water samples. The engineered material was characterized through XRD, EDX, and SEM. The EDX mapping was also used to examine the purity, surface texture, and focused elemental composition of the NiO/ZnO/rGO nanohybrid. The average size of the prepared material was calculated as 43.7 nm, which confirmed the nanometric size of the engineered nanohybrid material. The conductive behavior of the fabricated sensor NiO/ZnO/rGO/PtE was examined through electrochemical impedance spectroscopy (EIS) and cyclic voltammetry. The modified sensor revealed an excellent conductive nature with ohmic resistance calculated to be 412 Ω, which is lower than that of the bare electrode and GO/PtE (3628 and 2239 Ω, respectively). Under optimal parameters, the fabricated sensor showed excellent response for BPA. With a linear dynamic range of 0.07−30 μM, NiO/ZnO/rGO/PtE manifested the lowest possible detection limit found (4.0 nM). The analytical applicability of the proposed sensor was investigated in bottled and tap water. Furthermore, both the acceptable recovery values and anti-interference ability indicated the effectiveness and potential commercial utilization of NiO/ZnO/rGO/PtE. The recovery values for mineral and tap water were 97.0%, 99.0%, and 97.3% and 101%, 99.6%, and 98.7%, respectively.

“…Among the various detection methods, electrochemical methods have received extensive attention due to their fast detection speeds, ease of operation, and low detection costs [ 5 , 6 , 7 ]. For the sake of achieving high specificity in detection, some recognition elements with specific recognition capabilities such as antibodies [ 8 , 9 ], aptamers [ 10 , 11 ], enzymes [ 12 ], and molecularly imprinted polymers (MIPs) [ 13 , 14 , 15 ] have been extensively utilized.…”

In view of the great threat of chloramphenicol (CAP) to human health and the fact that a few producers have illegally used CAP in the food production process to seek economic benefits in disregard of laws and regulations and consumer health, we urgently need a detection method with convenient operation, rapid response, and high sensitivity capabilities to detect CAP in food to ensure people’s health. Herein, a molecularly imprinted polymer (MIP) electrochemical sensor based on a dual-signal strategy was designed for the highly sensitive analysis of CAP in milk. The NiFe Prussian blue analog (NiFe-PBA) and SnS2 nanoflowers were modified successively on the electrode surface to obtain dual signals from [Fe(CN)6]3−/4− at 0.2V and NiFe-PBA at 0.5 V. SiO2-COOH@MIPs that could specifically recognize CAP were synthesized via thermal polymerization using carboxylated silica microspheres (SiO2-COOH) as carriers. When the CAP was adsorbed by SiO2-COOH@MIPs, the above two oxidation peak currents decreased at the same time, allowing the double-signal analysis. The SiO2-COOH@MIPs/SnS2/NiFe-PBA/GCE sensor used for determining CAP was successfully prepared. The sensor utilized the interactions of various nanomaterials to achieve high-sensitivity dual-signal detection, which had certain innovative significance. At the same time, the MIPs were synthesized using a surface molecular imprinting technology, which could omit the time of polymerization and elution and met the requirements for rapid detection. After optimizing the experimental conditions, the detection range of the sensor was 10−8 g/L–10−2 g/L and the limit of detection reached 3.3 × 10−9 g/L (S/N = 3). The sensor had satisfactory specificity, reproducibility, and stability, and was successfully applied to the detection of real milk samples.
