“…Therefore, the progression of CML disease should be controlled by measuring the concentration of the IMAT drug at the plasma level. According to previous reports, monitoring IMB levels in real biological samples is of great environmental and clinical importance [6,7]. Various analyses, such as capillary electrophoresis, high-performance liquid chromatography, gas chromatography, Biosensors 2023, 13, 547 2 of 14 and fluorescence spectroscopy, have been used to measure the concentration of IMAT [8][9][10][11][12][13].…”

Imatinib mesylate, an anticancer drug, is prescribed to treat gastrointestinal stromal tumors and chronic myelogenous leukemia. A hybrid nanocomposite of N,S-doped carbon dots/carbon nanotube-poly(amidoamine) dendrimer (N,S-CDs/CNTD) was successfully synthesized and used as a significant modifier to design a new and highly selective electrochemical sensor for the determination of imatinib mesylate. A rigorous study with electrochemical techniques, such as cyclic voltammetry and differential pulse voltammetry, was performed to elucidate the electrocatalytic properties of the as-prepared nanocomposite and the preparation procedure of the modified glassy carbon electrode (GCE). A higher oxidation peak current was generated for the imatinib mesylate on a N,S-CDs/CNTD/GCE surface compared to the GCE and CNTD/GCE. The N,S-CDs/CNTD/GCE showed a linear relationship between the concentration and oxidation peak current of the imatinib mesylate in 0.01–100 μM, with a detection limit of 3 nM. Finally, the imatinib mesylate’s quantification in blood-serum samples was successfully performed. The N,S-CDs/CNTD/GCE’s reproducibility and stability were indeed excellent.

“…Various physical, chemical and biological treatment techniques methods such as coagulation, reverse osmosis, ionization exchange, photocatalysis, oxidation, adsorption and ozone treatments are used to remove dyes from water and wastewater (Mokif et al 2019;Vijayageetha et al 2014;Huang et al 2021;Torkian et al 2022;Chanikya et al 2021;Alwan et al 2022;Powar et al 2020;Ajel et al 2022). Most of these techniques are characterized by high efficiency in treating colored water, but their major disadvantage is the high operating cost.…”

In the current study, new zinc oxide/activated carbon (ZnO/AC) nanocomposites were successfully synthesized, using Pontederia crassipes leaves as a carbon source for synthesis of activated carbon. In addition, the extract of Pontederia crassipes leaves was obtained as reducing and capping agent in the synthesis of ZnO. The synthesized materials were investigated using various characterization techniques including XRD, FTIR, FE-SEM, EDX, BET-BJH, TEM and Raman, which proved the successful synthesis. The synthesized samples were applied as new nanoadsorbents for the uptake of Malachite Green (MG) and Congo Red (CR) dyes from aquatic media. The thermodynamic, adsorption isotherm and kinetic studies were conducted adopting the batch experiment method. The results showed that the optimum efficiency of removal of both dyes was achieved with ZnO/AC (10%) nanocomposite, which was found to be 98.87% for CR dye and 99.23% for MG dye. The thermodynamic analysis exhibited that adsorption process for both dyes is spontaneous. In addition, the results exhibited that the removal of CR onto ZnO/AC(10%) was exothermic, while that of MG was an endothermic. In the case of adsorption isotherms, the Freundlich model showed the best fit for both dyes with a high correlation coefficient (R2) of 0.99, suggesting heterogeneous surface of the synthesized nanoparticles. The kinetic analysis indicated that both dyes followed a pseudo-second-order kinetic model.

“…Acyclovir (ACV) with chemical structure of 2-amino-9-[(2hydroxyethoxy) methyl]−6,9-dihydro-3H-purin-6-one is known as an antiviral drug that is considered in the treatment of viral diseases, such as Harris zoster, Harris simplex, herpes, hepatitis. [1][2][3][4] This drug can be used in different ways, such as pre-oral, intravenous and topical but its improper dose causes adverse symptoms, including vomiting, diarrhea, urticarial, fainting and neurotoxicity. [5][6][7][8][9] Because of its structural closeness to guanine, an endogenous substance, and its high solubility in water, the isolation of this antiviral medication and its quantitative determination in biological samples are highly challenging.…”

In the world of medicine, the discovery of acyclovir, an antiviral medication often used to treat herpes infections, is very important. Accurate and sensitive detection are essential for patient safety since acyclovir is recognized for its possible adverse effects and toxicity at high dosages. A Cu metal-organic framework (MOF) doping with Fe3O4/SiO2 was prepared by direct Co-precipitation method. This binary Fe3O4-SiO2/Cu-MOF was analysis by scanning electron microscopy and X-ray diffraction spectroscopy, and this MOF was used to modify the glassy carbon electrode (GCE) surface. Modified GCE was used for the electrochemical monitoring of Acyclovir in the plasma samples. Acyclovir's electro-oxidation behavior was assessed using cyclic and differential pulse voltammetric techniques. A redox mechanism was postulated based on the effect of the potential scanning rate and solution pH on the voltammetric response of Acyclovir oxidation. A 0.03 μM limit of detection was acquired for Acyclovir analysis with a linear response in the range of 1-60 µM. Finally, acyclovir quantification in the blood serum samples was successfully performed.
