▎ 摘　　要

Purpose - This paper aims to provide details of recent developments in nanosensors based on graphene. Design/methodology/approach - Following an introduction, this paper first considers some of the motivations for using graphene in sensors. It then describes a selection of recently reported graphene nanosensors for detecting physical variables, gases, chemical species and biological agents. Finally, brief conclusions are drawn. Findings - Graphene exhibits a number of unique properties that make it an intriguing candidate for use in sensors. Research is still at a relatively early stage, but prototype sensors have been demonstrated which respond to numerous physical, molecular and biological variables. Originality/value - This paper provides a timely review of the use of graphene in sensors.
