“…The immobilization of enzymes onto the metal oxide/electrode surface is required because metal oxide nanocomposites offered a biocompatible environment for the enzymes to function on the electrode and improve the selectivity and sensitivity of the sensing electrode via enabling electron-transfer kinetics between the enzyme and the electrode. The resulting activity catalyses the electrochemical reduction or oxidation of the analyte [32][33][34]. In this review, key advancements, electrode fabrication, sensing mechanism, present challenges, and prospects of the transition metal oxide nanomaterials and nanocomposites-based electrochemical sensors towards the development of highly durable and reliable detection of biomarkers will be described.…”
