Exploring the Internet of Bio-Nano Things: Technologies, Applications, and Challenges

The term "Internet of Things" (IoT), which refers to networked devices and items with embedded computing capabilities used to expand the Internet to numerous application fields, has gained significant attention in the past 10 years. There are numerous application fields where extremely small, covert, and non-intrusive items are required, even as research and development for generic IoT devices continues. The idea of the Internet of Nano Things (IoNT), which is based on the networking of nanoscale devices, was motivated by the characteristics of freshly researched nanomaterials like graphene. Although IoNT devices facilitate several uses, their artificial character can be harmful in situations where their deployment may have unintended health or pollution repercussions. Based on synthetic biology and nanotechnology methods that enable the fabrication of biological embedded computing devices, this study introduces the unique paradigm of the Internet of Bio-Nano Things (IoBNT). Using biological cells and their metabolic functions, Bio-NanoThings holds the potential to facilitate applications including environmental pollution and toxic agent control, intrabody sensing, and actuation networks. An interface to the electrical domain of the Internet is made possible by the Internet of Biomolecules , a concept that is revolutionizing communication and network engineering. The present study presents new challenges for the development of effective and secure methods for information exchange, interaction, and networking within the biochemical domain. Single nanomachines’ capacities should increase as a result of connecting them and creating nanonetworks, since the information exchange that results will enable them to work together to achieve a shared objective. These days, systems typically use electromagnetic signals to encode, transmit, and receive data; nevertheless, molecular transceivers, channel models, or protocols use molecules in a revolutionary communication paradigm. To enhance comprehension of nanonetwork scenarios in biomedical applications, this article outlines the latest advances in nanomachines and their future architecture. Two applications for nanonetworks are also presented in order to emphasize the communication requirements between nanomachines: i) the Internet of NanoThings, a new networking paradigm that enables nanoscale devices to connect with preexisting communication networks, and ii) Molecular Communication, which involves the spread of chemical compounds such as drug particles.
