A high sensitive electroanalytical-based sensor for determination of isoprenaline was fabricated by modification of carbon paste electrode (CPE) by NiO-Pt-Pd/CNTs composite as conductive mediator and n-hexyl-3-methylimidazolium hexafluoro phosphate (NHIHP) as conductive binder. The NHIHP/NiO-Pt-Pd/CNTs/CPE was improved the oxidation signal of isoprenaline ⁓3.47 times and reduced oxidation overpotential of drug ⁓180 mV. The pH investigation confirmed that redox behavior of isoprenaline is depended of pH solution with equal value of electron and proton in redox mechanism. The NHIHP/NiO-Pt-Pd/CNTs/CPE was successfully used for determination of isoprenaline in the concertation range 0.003-300 µM with detection limit 0.9 nM by square wave voltammetric method. The standard addition results showed powerful ability of NHIHP/NiO-Pt-Pd/CNTs/CPE as an electroanalytical tool for determination of isoprenaline in the pharmaceutical and clinical samples with recovery data 98.76-105.06%.

Zolpidem is an imidazopyridine derivative, non-benzodiazepine and sedative-hypnotic medicine. It is a widely prescribed medication in adults used for the short-term treatment of a sleep problem called insomnia and frequent awakenings. In this work, the zolpidem was determined using Ag/ZnO nanoplates modified glassy carbon electrode (Ag-ZnO/GCE). Electrochemical behavior of the zolpidem was investigated by differential pulse voltammetry (DPV), chronoamperometry (CHA), and cyclic voltammetry (CV) using the Ag-ZnO/GCE. The results revealed that, the current responses of the zolpidem improved significantly due to the high catalytic activity and electron transfer reaction of nanoplates. The linear range of zolpidem was found to be from 0.1 µM to 500.0 µM with the detection limit of 0.03 µM. In addition, this original sensor showed numerous benefits such as reproducibility, high stability, and rapid response (20 s).

Hybrid composite based on graphene oxide (GO) and covalent organic framework (COF) [GO/COF] was developed via a simple solvothermal method, at which GO was applied as a platform to load COF based on melamine and terephthaldehyde. The synthesized hybrid nanocomposite was characterized by FT‐IR, XRD, EDX and SEM techniques. Morphological analyses carried out by SEM confirm the successful growth of COF over GO. Then, the resultant composite was employed as an amazing and cost‐effective catalyst in the condensation of several aldehydes with malononitrile and produced the corresponding coupling products in high yields (up to 84%) at room temperature under solvent‐free conditions with an amount of catalyst, 15 mg in a very short reaction time of 10 min. The catalyst could be reused without a noteworthy drop in catalytic activity at least eight times. The use of GO/COF catalyst outcomes under mild reaction conditions in very short reaction time, exceptional catalytic activity, high recyclability and an easy work‐up process for the Knoevenagel condensation.
