Nanostructured Metal Oxide-Based Hybrid Materials for the Fabrication of Electrochemical Biosensors

Dear Colleagues,

Recently, the design and fabrication of sensors, particularly electrochemical biosensors, have attracted the attention of the scientific community due to their excellent selectivity, sensitivity, and recovery rate in real samples. Moreover, the fabrication of electrochemical biosensors involves simple deposition techniques, such as the drop-casting method. Electrochemical biosensors also have various advantages over traditional methods in terms of their cost-effectiveness, simplicity, selectivity, sensitivity, and portability, and can be applied to environmental monitoring, biomedical diagnostics, and food quality monitoring applications. The electrode materials play a vital role in the fabrication of electrochemical biosensors. Nanostructured materials with a high larger surface area, stability, and conductivity are desirable for the fabrication of biosensors. Metal oxides are highly stable materials with decent conductivity and catalytic properties. The unique surface morphology of metal oxides may also facilitate electron transfer and enhance the sensitivity of biosensors. Therefore, it can be considered that metal oxides with unique morphological features or their hybrid composite materials may be used as sensing layers for the development of electrochemical biosensors. This Special Issue highlights the recent advances in the design, fabrication, and electro-catalytic performance of metal oxides and their hybrid materials for the determination of various environmnetal pollutants and biomolecules. The aim of this Special Issue is to update researchers on recent progress in the development of metal oxides-based biosensors for biomedical and environmental applications.
