Scaffold assisted synthesized metallic and semiconductor nanowires for electrochemical biosensing applications

Scaffold assisted synthesized metallic and semiconductor nanowires are one of the most promising nano-building blocks for energy conversion, storage devices, electronics, and biosensing applications. The demand of multi-purpose and multi-functional materials, scaffold assisted synthesized metallic and semiconductor nanowires have been designed and fabricated using different techniques. Among the class of nanowires, metal–polymer, metal–metal oxide, metal–semiconductor, metal–metal, and metal–semiconductor nanowires have been used for various purpose. In this chapter, a comprehensive study of scaffold assisted synthesized metallic and semiconductor nanowires using electrochemical technique have been discussed. Moreover, these nanowires have been discussed extensively for biosensing applications including sensing of glutamate in food products, biosensor for glucose detection, uric acid biosensor, immunosensor for sensing of nuclear matrix protein-22 (NMP-22) and electrochemical glucose biosensors. In spite of this, the sensor and actuators based on these nanowires have significant applications in electrical, thermal, opto-electronic, mechanical, and biomedical devices.
