Graphene-based Nanocomposite Sensors: Present, Past and Future Check Access

The present chapter comprehensively explains the fundamentals behind the modification and functionalization of graphene in the designing of sensors for sensing of different analytes through electrochemical and optical techniques. The nature of environmental, chemical and biosensing analytes is mentioned and a reasonable explanation of the requirement of their detection is given. The history of graphene, graphene nanocomposites, sensors, and biosensors, as well as graphene-based nanocomposite sensors is collectively discussed. The challenges and difficulties related to traditional sensors are taken into account with critical analysis of current graphene nanocomposite-based sensing research. A study of the past, present and future perspectives of graphene-based nanocomposite sensors is undertaken in this chapter.
