Biosensors have recently attracted much attention due to their applications in clinical diagnostics, toxicity analysis, food industries, environmental monitoring and quality control1‐3. Biosensors have the potential to replace or complement the classical analytical methods by simplifying or eliminating sample preparation protocols and making field testing easier and faster with significant decrease in costs per analysis. And nanobiotechnology is rapidly evolving to open new materials useful in solving challenging bioanalytical problems, including specificity, stability and sensitivity. In this context, nanomaterials are being increasingly used for the development of biosensors. Their use has extended into all areas of biosensor research. Among the various nanomaterials, nanostrutured metal oxides are being widely investigated for immobilization of biomolecules like proteins and single stranded DNA oligomers. Among the various nanostructured metal oxides, cerium oxide, zinc oxide, tin oxide have recently attracted much attention for the fabrication of miniaturized biosensing electrodes. I will focus on some of the recent results obtained at our laboratories relating to development of nano‐structured metal oxides based biosensors.
