  • Inspired by the chemistry of adhesive proteins in mussels, hydrogels can now be made to self-heal in water without the aid of metal chelates.

  • Mussels use strong filaments to adhere to rocks, preventing them from being swept away in strong currents. Here, the authors borrow and simplify chemistries from the mussel foot to create a one component adhesive system which holds potential for employment in nanofabrication protocols.

  • Interfacial water constitutes a formidable barrier to strong surface bonding, hampering the development of water-resistant synthetic adhesives. Here, the authors elucidate the precise time-regulated secretion of mussel adhesive proteins in Perna viridis, probing their surface structures and subsequent roles.

  • Mussel adhesion depends on secreted dopa-modified proteins, but the dopa groups are prone to oxidation, which decreases their stickiness. A second mussel protein is now shown to regulate the redox state of these adhesive groups by coupling thiol oxidation to dopa reduction.

  • Cation–π interactions are critical for the adhesion proteins of marine organisms, yet the energetics of cation–π interactions in underwater environments remains uncharted. Nanoscale force measurements and NMR spectroscopy reveal that interfacial confinement fundamentally alters the energetics of cation–π mediated assembly.

  • The squid beak displays a 200-fold stiffness gradient across its length. A battery of experiments, including ‘omics analysis and rheological measurements, now identifies two protein families that infiltrate and cross-link a porous chitin network to generate variable stiffness.

  • There is interest in the development of mussel inspired materials; however, this requires an understanding of the materials. Here, the authors report on an investigation into the properties of mussel cuticle from different species that challenges conventional wisdom about particle filled composites.

  • Synthetic polymers functionalized with mussel-inspired catechols have been shown to exhibit self-healing and adhesive properties, mediated by metal chelation, that are much needed in biomedical and environmental applications. Now, a metal-free approach to complete polymer self-healing underwater mediated by extensive hydrogen bonding in catechol-functionalized polyacrylates is reported.

  • Bioelastomers generally show elasticity similar to that of rubber, which originates from entropic forces linked to deformation. It is now shown that in the egg capsule of a large marine shell, the elasticity is instead based on a structural transition. The results could have a significant impact on engineering protective encapsulating systems inspired by natural elastomers.

  • Robust attachment between living tissues and inert materials is challenging to achieve. Here, Hwang and co-workers look at the molecular level between tissue and embedded byssal threads of Atrina pectinata and how this affects tenacity, toughness, and robustness.

  • Mussel reliance on catechol-functionalized proteins for adhesion in wet environments comes with advantages and risks. Catechol interactive versatility is an obvious benefit; the greatest risk is catechol oxidation, which is mitigated by an intrinsic redox homeostasis that repairs oxidative damage.
