Abstract

The birth of wireless communication systems nearly a century ago has transformed and redefined the way humans communicate and interact. This transformation has evolved over many years and has brought along not only seamless connectivity for human interactions but also communication between machines and devices. While these communication systems are manmade artifacts, the research community has more recently turned its attention to other communication strategies that have spontaneously evolved in nature. These are at the basis of the information flow among and within biological cells, the fundamental units of life, and their organization into more complex organisms. At the basis of these strategies, information is encoded into molecules and exchanged through chemical reactions and molecule transport processes. The molecular
