Synthesis of nano-ferrites-based materials: A new paradigm for electrochemical sensors

Résumé fourni par la source

Ferrite-based nanoparticles and their composites have emerged as highly versatile materials in the field of electrochemistry and electrocatalysis, owing to their unique structural, magnetic, and electronic properties. This review critically examines the wide-ranging applications of these nanomaterials, emphasizing how their intrinsic structural features influence their performance in various electrochemical and electrocatalytic processes. Special attention is devoted to the synthesis strategies employed for the fabrication of nano-ferrites, including sol-gel, hydrothermal, and co-precipitation methods. Each synthesis technique is discussed in detail concerning experimental setup, control over particle size, morphology, crystallinity, and the associated merits and limitations. Furthermore, the review provides a comparative analysis of the application of ferrite-based nanomaterials as electrochemical sensors, particularly focusing on their use in the quantification of pharmaceutical drugs in biological fluids and pharmaceutical formulations. The sensing performances for various critical drug molecules, such as dopamine, acetaminophen, anti-cancer agents like chlorambucil and doxorubicin, and antiviral drugs like ledipasvir, are systematically discussed. The merits, including superior sensitivity, selectivity, and operational stability, as well as the limitations associated with reproducibility and matrix interference, are comprehensively analyzed. Finally, a future perspective is presented, highlighting the key challenges and proposing strategic directions to further enhance the efficiency, stability, and real-world applicability of ferrite-based electrochemical sensors for pharmaceutical and biomedical analysis.
