Abstract
A bioinspired method of communication among biodevices based on fluorescent nanoparticles is herein presented. This approach does not use electromagnetic waves but rather the exchange of chemical systems—a method known as molecular communication. The example outlined was based on the fluorescence properties of carbon dots and follows a circular economy approach as the method involves preparation from the juice of lemon waste. The synthesis is herein presented, and the fluorescence properties and diffusion coefficient are evaluated. The application of carbon dots to molecular communication was studied from a theoretical point of view by numerically solving the differential equation that governs the phenomenon. The theoretical results were used to develop a prototype molecular communication platform that enables the communication of simple messages via aqueous fluids to a fluorescence-detecting biodevice receiver.
Highlights
Molecular communication (MoCo), as a general concept, refers to all the biological processes in which information is exchanged by means of molecular messengers [1], such as mRNA, ions, etc., or the chemical communication methods used by plants and animals based on pheromones or terpenes [2,3,4]
The predominant target application for artificial MoCo is biomedicine and cybernetics, and biological systems are the ideal environment for using information particles to connect bio-implanted devices and create networks according to the internet of things (IoT) approach [6]
We present here the transformation of a low-value waste into a high-value nanotechnology resource in the field of biomedicine. It was not the aim of this work to contribute to this innovation in the field of MoCo; importantly, we demonstrate the possibility of valorising a raw waste material in line with the concept of circular economics by providing it a second use via preparation of highly fluorescent carbon dots dots (CDs) for use in fields such as biomedicine
Summary
Molecular communication (MoCo), as a general concept, refers to all the biological processes in which information is exchanged by means of molecular messengers [1], such as mRNA, ions, etc., or the chemical communication methods used by plants and animals based on pheromones or terpenes [2,3,4]. This term has been used to describe bio-inspired artificial communication systems, in which information particles (messengers) encode and transfer information between a transmitter and a receiver [5].
