Trends in Development of Nanomaterial-Based Sensing Devices

In these decade, the nano materials find wide spread applications in the designing and development of the electrochemical sensors. In specific, the nano materials like gold, silver, iron nano particles, magnetic nano materials, carbon based nano materials and quantum dots finds variety of applications. This nano material has become a frontier subject to study, for material scientists. In these days electrochemical sensors finds wide spread applications. The conventional electrochemical sensors require the bulk samples, macro electrodes and sophisticated instruments to fabricate the sensor device. The integration of the electrochemical sensing and microelectrode provide a single platform to fabricate a miniaturized, eco-friendly, reusable, less cost, more sensitive, rapid detection and multiplex sensing device. These type of micro devices uses versatile materials, to draw electrodes using suitable fabrication technique. In this chapter, different trends to fabricate miniaturized electrochemical sensing device has been deliberately discussed. This chapter focus on the miniaturized device fabrication, plenty of applications in real time, interfacing automation, identifying of research gaps and the methods to fulfill them. The present chapter give complete details about the modern approaches of the device fabrication methods of the electrochemical sensors.
