“…This result aligns with previous research, confirming that the rate of the electrochemical reaction is primarily governed by the diffusion of reactants to the electrode surface. The close correspondence between the experimental slope value and the theoretical value of 0.5 provides strong evidence supporting the diffusion-controlled nature of the Oxyp oxidation process, distinguishing it from an adsorption-controlled process [ 19 ].…”

Background and purpose: In this study, we present an electrochemical sensor for the detection of oxypeucedanin (Oxyp) and prantschimgin (Pra), two natural furanocoumarin derivatives. The determination of the effects of these molecules on DNA is important to be potential drug candidates. Our research focused on exploring the electrochemical behaviour of these compounds and their interaction with DNA. Experimental approach: The electrochemical properties of Oxyp and Pra were systematically analyzed by evaluating their oxidation currents. Changes in the oxidation currents and peak potentials of guanine bases were monitored before and after interaction in the solution phase and at the electrode surface. Key results: The limit of detection (LOD) and limit of quantitation (LOQ) for Oxyp were determined to be 1.3 and 4.3 µg/mL, respectively. For Pra, the LOD and LOQ were found to be 20 and 68 µg/mL, respectively. Stability studies demonstrated that the Oxyp solution retained its oxidation capacity for over a month, whereas the Pra solution retained its oxidation capacity for nearly 120 min. Our findings suggest that Oxyp interacts with dsDNA, potentially through electrostatic interactions, showing promise as a potential drug candidate targeting DNA. On the other hand, the interaction of Pra with dsDNA requires further exploration to fully understand its mode of action. Conclusion: The electrochemical sensor developed in this study provides a reliable and efficient method for detecting and analysing the interaction of these natural compounds with dsDNA. Our research contributes to advancing the understanding of the interaction between natural furanocoumarins and dsDNA, laying the groundwork for the design and development of novel and effective DNA-targeted drugs.

“…The EIS experiment was carried out under open-circuit potential conditions, with a voltage perturbation amplitude of 10 mV and in the frequency range of 100 kHz–10 mHz, with 10 points per frequency decade. Furthermore, the inner sphere electron-transfer mechanism of the ferrocyanides is given to be mostly dependent on the electrode surface chemistry , and it is commonly used to verify the electron-transfer properties of materials − including materials based on phosphorus. ,− Therefore, we found this redox probe to be particularly valuable in differentiating the efficiency of surface modification protocols.…”

“…Just as for a voltage of 2.5 V (Figure 4), for chitosan deposition times of 1 and 2 min, it can be seen that in the anodic part of the CV diagram, there is oxidation of the electrode material (FLBP) at about 0.6 V due to incomplete coverage by the chitosan, in accordance with the literature. 47,60 By applying a constant voltage for more than 1 min, lower peak separations were obtained. Moreover, the j A /j C ratio decreases with the longer deposition time from 1 to 4 min (Table 3) and increase again at 8 min of deposition.…”

This study presents the preparation and characterization of fewlayer black phosphorus (FLBP) chitosan electrodes by controlled electrochemical deposition of chitosan nanoparticles on FLBP-modified glassy carbon electrodes. FLBP was prepared by solvent-assisted exfoliation of bulk BP and was further modified with chitosan forming together a nanocomposite, including easy crosslinking with nanomaterials and film-forming properties. Cyclic voltammetry was employed to analyze the kinetic properties of electrodes fabricated at different electrochemical deposition durations of chitosan, revealing distinct reduction and oxidation peaks using 10 V. The electrochemical impedance spectroscopy technique was employed to further characterize the investigated FLBP-chitosan nanocomposites, which provides valuable insights into the electrode material properties. The controlled electrochemical deposition of chitosan nanoparticles on FLBP-modified glassy carbon electrodes opens up possibilities for developing a wide range of electrochemical sensors and devices for energy storage applications.
