“…Graphene is oxidized and converted into graphene oxide (GO), this GO reacts with dyes, metal ions, organic pollutants, and inorganic pollutants and removes them from wastewater. 36 Hydroxyl and carboxyl groups are present on GO and they increase the removal efficiency. Two different hydrogen bonds are used in GO to interact with the pollutants.…”

Terbinafine (TER) is a well-known potent antifungal administrated for the oral and topical treatment of mycosessince. The present study introduced a novel graphene (Gr) nanosheet integrated carbon paste electrodes (CPEs) for sensitive voltammetric determination of TER in pharmaceutical formulations and surface water samples. On the surface of the Gr/CPEs, terbinafine recorded an irreversible anodic oxidation peak at 1.11 V following a pure adsorption-controlled reaction mechanism accompanied by the transfer of one-electron/proton as predicted by the molecular orbital calculations, scan rate, and pH studies. Integration of the carbon paste matrix with 7.0% graphene nanostructure improved the sensor performance by about 10 folds through the enhancement of the electroactive surface area and the electrocatalytic effect of graphene towards the electrooxidation of the TER molecule at the electrode surface. Details studies were carried out including the impact of the nature and content of the electrode modifier, pH, and the applied scan rate. The cited sensor showed improved sensitivity within the TER concentration range from 0.17 to 10.8 µg mL−1 with a limit of detection of 0.05µgmL-1. A prolonged operational lifetime with high measurement and fabrication reproducibility was reported. The specificity of the fabricated Gr/CPEs was evaluated in the presence of the TER degradation products and other excipients commonly present in pharmaceutical formulations. The reported improved sensor performance encourages the application of the presented voltammetric sensor for the quantification of TER in pharmaceutical formulations, biological fluids, and residues in surface water samples.

Pesticides are hazardous chemicals that are spread on crops to protect from pests or insects. These are widely used in agriculture as well as for domestic purposes, which not only affect plants and animals but also harm the human body. Therefore, detection of these harmful pesticides is of utmost importance. Conventional methods of pesticide detection are costly, time–consuming and need manpower to perform analysis; however, electrochemical sensing of pesticides is emerging as one of the best current approaches. Since, these sensors exhibit the capability of detecting pesticides onsite, easy fabrication, high selectivity and sensitivity, hence are preferred ones from the forensic point of view. Although, there have been several studies conducted on the sensing of pesticides but this study mainly focuses on electrochemical sensing of pesticides using specific nanomaterials such as nanoparticles, nanocomposites, metal–organic framework (MOF) and 2‐dimensional materials. Additionally, this review also comprises of the comparison of analytical conditions including limit of detection of the aforementioned technique, future perspectives and challenges associated with the development of next generation sensors. Therefore this review, in a broad perspective, provides information that would be useful for the fabrication of new electrochemical sensors and their applicability in the fields of chemistry, forensic science, food technology, material science, environmental science, nanoscience and biotechnology. From the study conducted through this review, it was observed that AuNPs are the mostly used nanoparticles where enzymatic nanosensor with coating of AuNPs along with fluorine doped tin oxide exhibited good activity for the detection of pesticides.
