Using Nano-Arrayed Structures in Sol-Gel Derived Mn2+ Doped Tio2 for High Sensitivity Urea Biosensor
Application of nanoscale materials for electrochemical biosensors has been grown exponentially due to high sensitivity and fast response time. In these applications, effective immobilization of biomolecules without altering bioactivity is the key in construction of stable and well-structured electrode materials for biosensor platform. These factors eventually controlled by the interaction effectiveness and determine selectivity and sensitivity of materials for potential application in the area of biomedical diagnosis. This demonstrates the need of tailoring architecture of electrode materials to develop heterogeneity which could provide multifunction for functionalized electrode materials for biological applications.
