“…The bare platinum electrode was modified through NiO/ZnO/rGO material via a drop casting method. , For the construction of the modified electrode, 5 mg of NiO/ZnO/rGO material was dispersed in 3 mL of DI water, followed by adding 50 μL of nafion solution as a binder. The dispersion of NiO/ZnO/rGO and nafion was sonicated for 30 min until the formation of a well-dispersed mixture.…”

“…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.

“…This customization enables the utilization of different monovalent interactions, including π–π stacking, cation–π interactions, CH–π interactions, and hydrogen bonding, to enhance the binding affinity and selectivity of calixarenes toward target guests. By leveraging these interactions, calixarenes offer a wide range of possibilities for fine-tuning molecular recognition and facilitating targeted interactions with guest molecules. − The p -tetrasulfonated calix[4]arene variant has four sulfonate groups attached to its structure, providing strong ion exchange capabilities and high water solubility. This functionalization enables selective ion transport and separation processes within the membrane.…”

Linezolid is most widely used antibiotic that inhibits different bacteria and micro-organisms. The overuse of linezolid causes several health complications, such as vomiting, tongue decolorization, and low blood glucose. An efficient and sensitive electrochemical sensor based on a NiO and reduced graphene oxide nanocomposite with a modified platinum electrode (NiO/rGO/PtE) was therefore developed for the monitoring of the linezolid drug. The confirmation of synthesis of graphene oxide and NiO/rGO was conducted through several physicochemical characterization techniques. The Fourier transform infrared spectroscopy results confirmed the Ni−O symmetric and antisymmetric stretching frequency at 741.4 and 732.1 cm −1 , Xray diffraction spectroscopy revealed exceptional crystallinity, while the size of the prepared materials, which was confirmed through atomic force microscopy, was determiend to be 1.675 nm. The incorporation of NiO into GO sheets is visualized through scanning electron microscopy images. Cyclic voltammetry and electrochemical impedance spectroscopy techniques were implemented to assess the electrochemical activity and the conductivity of NiO/rGO/PtE. Under the optimized conditions (phosphate buffer with a pH value of 6.0, scan rate of 70 mV/s, and linear dynamic range (LDR) value between 0.1 and 90 μM), the engineered sensor NiO/rGO/PtE manifested an excellent response for linezolid. The limit of detection (LOD) value of proposed technique for monitoring linezolid was computed to be 0.0031 μM, which was the lowest possible detection limit, compared to the literature. The anti-interference pattern and long-term stability further demonstrated the efficiency and reliability of NiO/rGO/PtE. The analytical application of NiO/rGO/PtE for linezolid was examined in urine samples as well as a commercial pharmaceutical sample. The sensitivity and reliability at repeated runs of modified sensor suggest that it could be used for the onsite detection of linezolid. Experiments have been conducted regarding the application of a fabricated NiO/rGO/PtE sensor as an effective and simple detection tool for antibiotics with a lower LOD than that of the reported electrochemical sensors for linezolid.
