Internet of Bio-Nano Things: A review of applications, enabling technologies and

key challenges

Pages 1-24
Murat Kuscu, Bige Deniz Unluturk
Internet of Bio‑Nano Things (IoBNT) is envisioned to be a heterogeneous network of nanoscale and
biological devices, so called Bio‑Nano Things (BNTs), communicating via non‑conventional means,
e.g., molecular communications (MC), in non‑conventional environments, e.g., inside human body. The
main objective of this emerging networking framework is to enable direct and seamless interaction with
biological systems for accurate sensing and control of their dynamics in real time. This close interaction
between bio and cyber domains with unprecedentedly high spatio‑temporal resolution is expected to
open up vast opportunities to devise novel applications, especially in healthcare area, such as intrabody
continuous health monitoring. There are, however, substantial challenges to be overcome if the
enormous potential of the IoBNT is to be realized. These range from developing feasible
nanocommunication and energy harvesting techniques for BNTs to handling the big data generated by
IoBNT. In this survey, we attempt to provide a comprehensive overview of the IoBNT framework along
with its main components and applications. An investigation of key technological challenges is
presented together with a detailed review of the state‑of‑the‑art approaches and a discussion of future
research directions.

Enabling molecular communication through chirality of enantiomers

Pages 25-32
Valeria Loscrı, Anna Maria Vegni

With the advancement of nanotechnology, there has been fervid research activity on new
communication paradigms suitable for new challenging contexts, such as biological systems. Among
different approaches, the most considered has been artificial Molecular Communication, where entities
such as synthetic molecules, enzymes, hormones, bacteria etc. are functionalized in order to implement
information exchange with the surrounding system and with other entities. In this context, it is
interesting to analyze specific features that could be exploited for effective communication paradigms.
In this paper, we focus on chiral molecules (a.k.a. enantiomers) as novel enablers for a molecular
communication paradigm. Chirality is an interesting and appealing feature existing in nature and that
can be replicated with strong emphasis in new types of materials, such as metasurfaces and
metamaterials. A deep knowledge of chirality features and how chiral molecules interact with each
other or with achiral molecules provides insights into designing a new molecular communication
technique suitable for biological environments. In this contribution, we will highlight the main
applications of chiral molecules and we will present chiral features as the viable way for realizing a
nanocommunication system.
