Abstract

Nanotechnology is playing an increasing important role in the development of nanosensors. Recently, electrochemical biosensors based on nanostructured metal oxides gained much attention in the field of health care for the management of various important analyte in a biological system. The unique properties of nanostructured metal oxides offer excellent prospects for interfacing biological recognition events with electronic signal transduction and for designing a new generation of bioelectronics devices. The purpose of the study is to evaluate the sensing properties of different nanoporous based materials doped with different metal oxide nanoparticles towards the electrochemical detection of various biological and environmental molecules and how such devices have enabled the achievement of high sensitivity and selectivity with low detection limits. Conclusion and the significance of the study produced an observation that the sensitivity and performance of nanostructured metal oxide based sensors is improved in the presence of these materials. The use of these metal oxide nanostructured materials has allowed the introduction of many new signal transduction technologies in biosensors.
