  Internet of Bio-Nano Things (IoBNT) is a transformative communication
framework, characterized by heterogeneous networks comprising both biological
entities and artificial micro/nano-scale devices, so-called Bio-Nano Things
(BNTs), interfaced with conventional communication networks for enabling
innovative biomedical and environmental applications. Realizing the potential
of IoBNT requires the development of new and unconventional communication
technologies, such as molecular communications, as well as the corresponding
transceivers, bio-cyber interfacing technologies connecting the biochemical
domain of IoBNT to the electromagnetic domain of conventional networks, and
miniaturized energy harvesting and storage components for the continuous power
supply to BNTs. Graphene and related materials (GRMs) exhibit exceptional
electrical, optical, biochemical, and mechanical properties, rendering them
ideal candidates for addressing the challenges posed by IoBNT. This perspective
article highlights recent advancements in GRM-based device technologies that
are promising for implementing the core components of IoBNT. By identifying the
unique opportunities afforded by GRMs and aligning them with the practical
challenges associated with IoBNT, particularly in the materials domain, our aim
is to accelerate the transition of envisaged IoBNT applications from
theoretical concepts to practical implementations, while also uncovering new
application areas for GRMs.
