Rapid and reliable detection of 5mC in the presence of cytosine is of great importance in biomedical research and clinical diagnosis. In this study, an electrochemical method was developed for the determination of 5mC. Different voltammetric techniques, especially differential pulse voltammetry (DPV) and square wave voltammetry (SWV) were used to investigate the electrochemical behaviour of 5mC. The study investigated the redox properties of 5mC in different pH media, in the range of 2.00–11.00 on disposable PG electrodes. The results show that the proposed method for voltammetric determination of 5mC in the presence of cytosine is an environmentally friendly and practical tool for monitoring epigenetic changes.

Batteries are regarded as an affordable, practical, and effective way to meet the growing needs for energy storage. Nanocomposite materials hold significant promise for both research and practical applications because of their superior performance, diverse composition, and structural benefits. NaCrSnNiCeO<small>₂</small> and NaCuFeNiCeO<small>₂</small> nanocomposites bring scientific innovation due to their peculiar structure, which incorporates cerium and multimetal synergy to enhance the electrochemical parameters. This research can pave the way for the use of these multimetal oxides as advanced electrode materials in energy storage systems by elucidating the effect of cation substitutions, such as Cu, Cr, Fe, and Sn, on their structure, conductivity, and redox activity. In particular, multi-component nanocomposites possess distinct features that make them beneficial for energy storage systems. In this work, NaCrSnNiCeO<small>₂</small> and NaCuFeNiCeO<small>₂</small> nanocomposites were synthesized <em>via</em> the sol–gel approach. The characterization of the prepared nanocomposites was done by employing FTIR, XRD, XPS, and SEM techniques, while the electrochemical performances of the prepared samples are analyzed by utilizing CV, GCD, and EIS techniques.

Employing advanced synthesis methods and extensive characterization, the paper demonstrates a specific capacitance and energy density that is higher than normal along with an increased cycling stability. Furthermore, a focus on economical and abundant feedstock and green chemistry in this research aims at formulating sustainable answers for next-generation energy storage technologies.
