Dissipative bio-inspired supramolecular materials — •Marta Tena-Solsona, Benedikt Reiss, and Job Boekhoven — Technische Universität München
Synthetic self-assembled supramolecular materials have enormously developed during last decades. Applications of them are found in healthcare opto-electronics, and a wide range of fields. Although the behavior of these man-made materials is well-known, they are far from competing with biological counterparts. Especially, concerning spatio-temporal control, responsiveness, or adaptivity against external stimuli. The main differences between both type of systems lie in the energy balance. While most artificial assembled materials operate close to the thermodynamic equilibrium, many of the more advanced biological machineries are kinetically governed by self-assembly processes. These processes require a constant input of energy in order to be sustained, and to continuously dissipate energy. This dissipative mode of self-assembly requires specific design rules which are not fully understood in chemically driven man-made materials. Therefore, the design of these dissipative self-assembled systems remains challenging and the number of man-made examples is still limited. Our work focuses on translating the interesting properties biology offers, to the fully synthetic dissipative assemblies. We have designed a chemical reaction network based on small molecules that forms transient, far from-equilibrium materials, by consuming a chemical fuel. The dissipative nature of our system allows us to spatio-temporary control these assemblies which are of colloidal nature or hydrogels.
