The advantages conferred by the physical, optical and electrochemical properties
of graphene-based nanomaterials have contributed to the current variety of
ultrasensitive and selective biosensor devices. In this review, we present the
points of view on the intrinsic properties of graphene and its surface
engineering concerned with the transduction mechanisms in biosensing
applications. We explain practical synthesis techniques along with prospective
properties of the graphene-based materials, which include the pristine graphene
and functionalized graphene (i.e., graphene oxide (GO), reduced graphene oxide
(RGO) and graphene quantum dot (GQD). The biosensing mechanisms based on the
utilization of the charge interactions with biomolecules and/or nanoparticle
interactions and sensing platforms are also discussed, and the importance of
surface functionalization in recent up-to-date biosensors for biological and
medical applications.
