Robustness in supramolecular assemblies far-from-equilbrium — •Job Boekhoven, Marta Tena-Solsona, Benedikt Rieß, and Raphael Grötsch — TUM, Chemistry Department, Garching, Germany

We will describe supramolecular assemblies that can only exist far-from-equilibrium driven by a chemical reaction network. As a result of their dissipative nature these assemblies are intrinsically unstable and can only be sustained by constant consumption of energy. We found that these assemblies can exert feedback on the reaction network that drives their own formation or degradation. This feedback can increase the robustness of the assemblies, and thus increase the survival time of the structures, compared to assemblies without this feedback. With this minimalist approach, we aim to study how typically life-like features, like robustness, oscillatory behavior and self-replication can emerge from simple, non-biological components.
