Nanotechnology is enabling us to devise ever-smaller devices to interact with the universe at molecular resolution. Though small enough to penetrate into cells, these devices individually are of limited capability. To unleash the full potential of nanotechnology, communication among nanomachines is a must. This would enable more complex applications, e.g., continuous health monitoring with intrabody nanosensor networks. Internet of Nano Things (IoNT), which defines these networks of nanomachines, such as nanobiosensors and engineered bacteria, integrated with the Internet infrastructure, has seen tremendous interest recently. IoNT is set to transform the way we connect with and understand the world at the bottom. However, conventional electromagnetic (EM) communication techniques, proved impractical for nanoscale due to antenna size and power limitations and large propagation losses. On the other hand, Nature itself provides a robust way of nanocommunication, i.e., Molecular Communications (MC), which is the common communication modality among living cells ranging from our own neurons to bacteria. Using the same language with living cells by encoding, transmitting and receiving information using molecules provides an energy efficient and reliable nanocommunication, even at harsh biological environments, where we expect most impactful medical applications of IoNT would operate.

Although there is tremendous interest in this field accompanied by a large body of theoretical work to devise communication methods for MC, no working prototype of an artificial MC has come to date. On the other hand, MC brings about unique challenges resulting from its highly complex, nonlinear, time-varying channel properties due to the discrete nature of information carriers, substantial channel memory and peculiarities of molecular interactions at nanoscale, that cannot be always tackled by conventional ICT tools. This leaves a huge question mark over the reliability of the existing MC methods, which are mostly adopted from conventional EM communications and not validated with practical MC devices.

Therefore, there is an urgent need for practical MC devices at micro/nanoscale, to close this gap between theory and practice in order to unleash the envisioned applications of IoNT and MC. Hence, in this project, we set out to implement the first working prototype of a micro/nanoscale MC system.
