| Summary: | Owing to their extraordinary electrical, chemical, optical, mechanical and structural
properties, graphene and its derivatives have stimulated exploding interests in their sensor
applications ever since the first isolation of free-standing graphene sheets in year 2004.
This article critically and comprehensively reviews the emerging graphene-based electrochemical
sensors, electronic sensors, optical sensors, and nanopore sensors for biological or chemical
detection. We emphasize on the underlying detection (or signal transduction) mechanisms, the
unique roles and advantages of the used graphene materials. Properties and preparations of
different graphene materials, their functionalizations are also comparatively discussed in view
of sensor development. Finally, the perspective and current challenges of graphene sensors are
outlined (312 references). |
