“…Graphene has also been utilised as the basis of sensors directed to the measurement of ciprofloxacin. For example, Zokhtareh and co-workers 31 have developed a bulk modified CPE with graphene nanosheets and Fe 3 O 4 nanoparticles, as shown within Fig. 4A.…”

“…4B(a–c), the authors proposed that the electrochemical detection was promoted by the negatively charged group on the surface of the graphene nanosheets reacting with the positively charged ciprofloxacin, facilitating the oxidation process. 31 Furthermore, a reaction occurs between hydroxyl groups on the surface of the iron oxide nanoparticles and the protonated N–H group on the ciprofloxacin. 31 The authors report that the sensor measures ciprofloxacin over the range 0.01–20 μM with a LOD reported to be low, at 1.8 nM (see Fig.…”

The measurement of glucose concentration is a fundamental daily care for diabetes patients, and therefore, its detection with accuracy is of prime importance in the field of health care. In this study, the fabrication of an electrochemical sensor for glucose sensing was successfully designed. The electrode material was fabricated using polyaniline and systematically characterized using scanning electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and UV-visible spectroscopy. The polyaniline nanofiber-modified electrode showed excellent detection ability for glucose with a linear range of 10 μM to 1 mM and a detection limit of 10.6 μM. The stability of the same electrode was tested for 7 days. The electrode shows high sensitivity for glucose detection in the presence of interferences. The polyaniline-modified electrode does not affect the presence of interferences and has a low detection limit. It is also cost-effective and does not require complex sample preparation steps. This makes it a potential tool for glucose detection in pharmacy and medical diagnostics.

“…CIP is regarded as an electroactive molecule that may be evaluated electrochemically due to its piperazine ring that oxidizes. Consequently, the electrochemical determination of CIP at the surface of electrodes has been reported by a number of researchers [12] . Different working electrode (WEs) such as screen‐printed electrodes (SPEs), gold electrodes (AuE), glassy carbon electrodes (GCEs) among others have been reported for electrochemical sensing platform.…”

Herein, a new electrochemical sensing system based on lutetium copper nanoparticles supported on hexagonal boron nitride (Lu‐Cu@h‐BN) was designed for the sensitive detection of ciprofloxacin (CIP) antibiotic. A simple hydrothermal method was used to synthesize the nanocomposite. The structural and morphological characteristics of the as‐prepared nanocomposite were investigated using various analytical techniques such as Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), scanning electron microscopy (SEM), and X‐ray photoelectron spectroscopy (XPS). The newly developed Lu‐Cu@h‐BN nanocomposite was used as an electrode modifier for sensing and signalling of CIP. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used to study the electrochemical activities of the bare GCE, Cu‐h‐BN/GCE, Lu‐h‐BN/GCE, Lu‐Cu/GCE, and Lu‐Cu@h‐BN/GCE. The electro‐oxidation of CIP on electrode surface exhibited an irreversible, diffusion‐controlled process. The sensor system obtained a wider linear range of (0.05–100 μM) with a lower detection limit value of 0.03 μM and sensitivity 0.7443 μA μM−1 cm−2. Furthermore, the sensor demonstrated an excellent selectivity, good stability, and reproducibility, with acceptable recoveries of 96 % to 104 % in real water sample analysis.
