Abstract

Biological communication is an indispensable component of intra- and extracellular regulation of life. Inspired by such complicated control networks, systems chemistry has begun to advance tools for autonomous networks by developing communication protocols between molecular entities to up- and downregulate functions (simple catalysis, dual catalysis, time-encoded emission). However, up to now these protocols remain relatively simple, indicating that there will be a long way to self-sustaining and autonomous functional systems. This review focuses on communication in artificial multicomponent systems that operate under either equilibrium or dissipative conditions, detailing the design principles for their operations. Finally, we discuss the key differences between biological and artificial signaling, emphasizing the limitations of artificial signaling and suggesting future directions in the field of artificial signal transduction.
