Advances in the Analysis of Pharmaceuticals by Using Graphene-Based Sensors

Safe and effective use of drugs relies on proper pharmaceutical analysis. Graphene has been extensively used to construct sensors for this purpose. Over the years, a large variety of pharmaceutical sensors have been developed from graphene or its derivatives. This article reviews the current status of sensor development from graphene and its derivatives, and discusses the use of graphene-based sensors in pharmaceutical analysis. It is hoped that this article offers not only a snapshot of recent advances in the fabrication and use of graphene-based sensors, but also provides insights into future engineering and optimization of the sensors for effective pharmaceutical analysis.
