“…However, electrochemical sensors have drawbacks in quantifying drug compounds such as low reduction/oxidation current and high overpotential, which must be circumvented. The sensor functionalization can be prospective method to monitor the conventional drug dosage (Bayraktepe, 2020;Fathi et al, 2020;Foroughi et al, 2021a;Foroughi et al, 2015;Li et al, 2022;Maaref et al, 2018;Moarefdoust et al, 2021). Nanomaterials have shown specific physical and chemical characteristics in a variety of fields (Akca et al, 2021;Farvardin et al, 2020;Foroughi and Jahani, 2022;Foroughi and Ranjbar, 2017;Mei et al, 2022;Salajegheh et al, 2019;Zhou et al, 2022).…”

Detection of DNA molecules and possible chemotherapy-induced changes in its structure has been the goal of researchers using rapid, sensitive and inexpensive approaches. Therefore, the aim of this study was to fabricate a new electrochemical DNA biosensor using pencil graphite electrodes modified with polypyrrole/Ce doped hexagonal nickel oxide nanodisks or PP/Ce-doped H-NiO-ND composites for determination of Abemaciclib (AMC) and ds-DNA molecules. The DNA biosensor was prepared by immobilizing ds-DNA on the surface of PP/Ce-doped H-NiO-ND/PGE. Differential pulse voltammetry (DPV) was used to electrochemically detect AMC. The results elucidate the extremely high sensitivity of the ds-DNA/PP/Ce-doped H-NiO-ND/PGE biosensor to AMC, with a narrow detection limit of 2.7 nM and a lengthy linear range of 0.01–600.0 μM. The admirable performance of as-fabricated biosensor could be related to the active reaction sites and the unique electrochemical response related to the nanocomposites by enhancing ds-DNA stabilization and accelerating electron transfer on the surface of electrode.

It is crucial to design fast, sensitive and affordable deoxyribonucleic acid (DNA) recognition instruments, and elucidate changes in DNA structure, for studying the interaction between DNA and chemotherapy drugs. Therefore, a DNA biosensor, based on a carbon paste electrode (CPE), modified with raspberry‐like indium(III)/nickel oxide hierarchical nano‐structures (In3+/NiO RLHNSs) was constructed. An electrochemical readout should then give information on the interactions between anticancer drugs and double‐stranded (ds)‐DNA. The morphology as well as the electrochemical description of this new biosensor is described. Based on experimentally determined optimal conditions, ds‐DNA modified with In3+/NiO RLHNSs/CPE was used to evaluate the binding interaction of nilotinib, as an anti‐cancer drug, with DNA through differential pulse voltammetry (DPV), UV‐Vis spectroscopy, viscosity measurements and a computational docking process. The analyses indicated the linearity of the guanine oxidation signal at nilotinib concentration is given between 0.01 and 50.0 μm, with the limit of detection (LOD) equal to 0.62 nm. Additionally, the equilibrium constant (K) for the binding was determined to 1.5×104 m−1. Through the quantitative measurement of nilotinib in serum samples with a high recovery rate of 101.3–98.0 %, the applicability of this approach was demonstrated. As a whole, this DNA biosensor may be promising for various bio‐interactions.

“…The conventional methods such as radioimmunoassay, surface-enhanced Raman spectroscopy (SERS), and other chromatographic techniques have already been employed to determine fentanyl in biological matrices such as blood and urine ( Stiller et al, 1990 ; Saraji and Boroujeni, 2011 ; Haddad et al, 2018 ). Among these, special attention has been paid toward the electrochemical method for the fentanyl determination because of sensitivity, selectivity, low cost, rapidity, and safety ( Foroughi et al, 2015 ; Foroughi and Ranjbar, 2017 ; Jahani, 2018 ; Maaref et al, 2018 ; Farvardin et al, 2020 ; Foroughi et al, 2021a ; Moarefdoust et al, 2021 ; Santana et al, 2021 ; Dalkiran and Brett, 2022 ; Foroughi and Jahani, 2022 ; Jahani et al, 2022 ). It is very important to choose the right platform in the electrochemical method, for example, the pencil graphite electrode (PGE) is known as a suitable substrate in electrochemical applications with unique properties such as broad potential range and low background current ( Antherjanam and Saraswathyamma, 2022 ).…”

Fentanyl was successfully determined in the current effort based on hexagonal NiO nanodisks (HG-NiO-NDs) fabricated by the hydrothermal protocol. The synergism of HG-NiO-NDs with multiwall carbon nanotubes (MWCNTs), large specific surface area, and active material enabled the electrochemical sensor to show potent electrochemical behavior. Admirable performance was found for the fentanyl measurement by the MWCNT and HG-NiO-ND-modified pencil graphite electrode (MWCNT/HG-NiO-ND/PGE). The correlation of oxidation currents with the pH value, concentration, and sweep rate of supporting electrolytes was determined for the optimization of conditions to detect fentanyl. The surfaces of modified and unmodified electrodes were characterized as well. The diffusion-control processes were confirmed on the basis of anodic peak findings. The results also revealed a two-electron transfer process. The linear range was obtained to be 0.01–800.0 μM for the fentanyl concentrations on the developed electrode, with the sensitivity of 0.1044 μA/mM/cm2. The limit of detection (S/N = 3) was 6.7 nM. The results indicated the ability of the modified electrode to fabricate non-enzymatic fentanyl sensor applications.
