Currente fforts to design functional molecular systems have overlooked the importance of coupling out-ofequilibrium behaviour with changes in the environment. Here, the authors use an oscillating reaction network and demonstrate that the application of environmental forcing, in the form of periodic changes in temperature and in the inflow of the concentrationo fo ne of the network components, removes the dependency of the periodicity of this network on temperature or flow rates and enforces as table periodicity across aw ide range of conditions. Coupling a system to ad ynamic environmentc an thusb eu sed as a simple tool to regulate the output of an etwork. In addition, the authors show that coupling can also induce an increase in behavioural complexity to include quasi-periodic oscillations.

“…In its finite lifetime, the metastable product is capable of self-assembly, resulting in dynamic assemblies that exchange building blocks rapidly and remodeling dynamics regulated by the kinetics of the reaction cycle. For example, in the dissipative self-assembly of fibers, [19] behavior reminiscent of dynamic instabilities in microtubules , [20,21] and oscillatory behavior between morphologies [22] has been observed. Other examples of recently described dissipative assemblies include active droplets, [23] hydrophobic colloids, [24] autocatalytic micelles, [46] the formation of clusters of nanoparticles, [25,26] DNA-based hydrogels [27,28] and supramolecular polymers.…”

Synthetic lipid membranes have served as important models for cellular membranes. However, these static membranes do not recapitulate the dynamic nature of the biological membranes which are frequently remodeled to support cellular function. An ideal membrane model would thus also display dynamic exchange of lipids. In this work, we achieve such a system by coupling the self‐assembly of peptides into membranes with a chemical reaction cycle. The reaction cycle activates and deactivates the peptides for self‐assembly at the expense of a chemical fuel. The resulting membranes are dynamically remodeled, and, over their 40 min lifetime, they emerge, grow, and are torn apart before they eventually decay.

“…Moreover, due to the continuous formation of the building blocks, the assemblies can undergo dynamic behavior if they exert minimal feedback on their reaction cycle. For example, if the assemblies enhance their formation and slow down their deactivation, exciting behavior like oscillations can spontaneously emerge …”

In molecular self‐assembly, molecules interact with each other by non‐covalent interactions to form larger structures. The process occurs in‐equilibrium, which means that molecules can leave the assembly and reassemble elsewhere, but that occurs on average with equal rates. For self‐assembly, peptides have proven to be a particularly useful building block, in part because of their versatility. Biology also uses self‐assembly to create functional materials. For example, components of the cytoskeleton, like actin filament and microtubules, are self‐assembled proteins. In other words, biology uses the same building blocks and design rules as supramolecular chemists to create functional structures. However, biological assemblies are vastly more complex than their synthetic counterparts. The discrepancy is in part because proteins are more complex than the peptides we use as building blocks. Another contributing factor to the difference in complexity is that most assemblies in living systems exist out of equilibrium. To use peptides for complex functions as biology does, we should understand and be able to create peptide assemblies out of equilibrium. In this work, we review recent advances towards the creation of peptide assemblies that exist out of equilibrium driven by an external energy source.
