Graphene and derivatives

© 2019 Elsevier Ltd All rights reserved. Graphene and related derivatives, such as graphene oxide and reduced graphene oxide, have come to the forefront of research in sensor applications during recent years. The rapidly growing activities in this area are due to the promising surface functionalization of these materials and their obvious success in electrochemical, electrical and optical sensors to date. In this article, we critically review the latest developments in the use of these materials for sensing technology, including chemical sensors and biosensors and their applications in security, environmental safety and diseases detection and diagnosis.
