  • Chemical systems can show complex behaviour that is not seen in individual molecules or reactions. Helena S. Azevedo, Sarah L. Perry, Peter A. Korevaar, and Dibyendu Das report on the emergence of this complex behaviour, which was discussed at the Virtual Symposium on Systems Chemistry

  • Constructing synthetic mimics of membraneless organelles using small molecules can contribute towards our understanding of active phase separation and their role in the chemical emergence of compartments. Herein, the authors develop a model of synthetic membraneless organelles as non-equilibrium droplet phase which are accessed via homotypic interactions between small activated molecule and short peptides.

  • Biological cofactors such as dihydronicotinamides are exploited by extant enzymes as hydride transfer agents and electron carriers but are generally inefficient to facilitate any reactions on their own. Here, the authors report short peptide-based amyloid nanotubes featuring exposed arrays of cationic and hydrophobic residues that can bind small hydride transfer agents (NaBH4) to facilitate efficient reduction of ester substrates in water.

  • The study of the network dynamics of complex systems formed by simple chemicals can contribute to our understanding of complex behavior from simple organic reactions. Here, built on the minimal building blocks, the authors describe a system with periodic (dis)assembly utilizing feedback loops controlled by time-delayed catalysis and pH-driven assembly.

  • Design of rewritable wettability pattern of low surface tension liquids is a challenging task to achieve. Here, authors introduced a chemically reactive crystalline network of polymer to develop rewritable and liquid-specific wettability pattern via spatially selective chemical modification.

  • Nanomotor chassis constructed from biological precursors and powered by biocatalytic transformations can offer important applications in the future. Here, the authors prepare short-peptide-based cross β amyloid nanomotors which can host dedicated enzymes with orthogonal substrates for motility and navigation.

  • Simple peptides are shown to assemble into well-defined amyloid phases with paracrystalline surfaces that can catalyse reactions in an enantioselective manner. Modifying individual amino acids in the building blocks enables the structure of the assembled aggregates, and the reactions that they can catalyse, to be controlled predictably.

  • The origins of complex life forms from simple chemicals remain one of the most enigmatic mysteries. This Review explores how non-equilibrium chemical-based systems can exhibit living matter-like properties with an outlook that connects the possibility of diversification, adaptation and evolution.
