Carbon Quantum Dots from Lemon Waste Enable Communication among Biodevices

A bioinspired method of communication among biodevices based on fluorescent nanopartides 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.
