  • Here the authors design tripeptides that form dynamic soluble dispersions and undergo phase separation upon drying to assemble into porous particles. This evaporation-driven emulsification can be harnessed to encapsulate and stabilize biomolecules.

  • The four-letter molecular code of DNA and the twenty-letter expression language of peptides have inspired the development of two thriving, but distinct, branches of nanotechnology; a technique that combines the two approaches could lead to robust, scalable materials with unique optoelectronic properties.

  • The cell's dynamic skeleton, a tightly regulated network of protein fibres, continues to provide inspiration for the design of synthetic nanostructures. Genetic engineering has now been used to encode non-biological functionality within these structures.

  • Supramolecular gels show promise in diverse areas, including healthcare and energy technologies, owing to tunable properties that arise directly from the organization of their building blocks. Researchers have now been able to control this behaviour by combining enzymatic catalysis with molecular self-assembly. Although it seems counter-intuitive, gels that assembled faster showed fewer defects.

  • Peptides that self-assemble into nanostructures are of interest for many applications, including ones relevant to cosmetics, food, biomedicine and nanotechnology. Now, computational tools have been developed that enable peptide sequence space to be rapidly searched for supramolecular properties and this approach has been used to identify unprotected tripeptide hydrogelators.

  • The production of functional molecular architectures through self-assembly is commonplace in nature, but it is still a major challenge to achieve similar complexity in the laboratory. It has now been shown that reversible enzyme-catalysed reactions can drive synthetic self-assembly. This approach could ultimately lead to the fabrication of functional nanostructures with enhanced complexities and fewer defects.

  • The interactions of sugars and proteins underlie many biological processes, and cataloguing them is a daunting task. A technique for attaching sugars to microarrays offers a promising, high-throughput solution.

  • Experiments and molecular dynamics simulations show that the dehydration-induced actuation of nanoporous tripeptide crystals is a result of pore contraction caused by the strengthening of the water hydrogen-bonding network inside the pore, which creates mechanical stress that deforms the crystal lattice.

  • Living systems create exceptional materials from simple amino acid building blocks. This Review explores how a systems-based approach — considering peptide, solvent and environment, and integrating computation and experimentation — can unlock peptide sequence space as a universal materials assembly code, enabling designs beyond biology’s natural scope.

  • A balance between order and disorder provides living materials with just the right amount of disorder needed to sustain life. This feature is currently not found in synthetic materials. Now, a route to the production of composite membranes that are simultaneously stiff and reconfigurable upon contact has been developed.

  • Fluorescence-based oligonucleotide probes, also known as molecular beacons (MBs), are popular for detecting nucleic acids with high specificity. Here, the authors demonstrate self-sequestration of MB-based biosensors and target strands within peptide-based coacervates, increasing local concentrations and significantly increasing the sensitivity and kinetics of the DNA biosensors.
