Remote communication between electronic devices is an open and active research subject. Nowadays we mainly communicate by transferring information via electromagnetic communication. However, this approach is not universally applicable. Nature faced and solved this problem by means of a strategy based on the release molecules acting as “chemical messengers”. Even if the biological communication networks are still too complex to be replicated, in all our views, bio-inspired molecular communication represents definitively a very promising strategy. In this project we perform a critical analysis on the problem of molecular communication through body fluids focusing on the selection and synthesis of a capable molecular messenger.
