Intertwined polymers and nanosheets create skin-like self-healing hydrogels
The artistic representation of the moebiusling hydrogel formed by self-healing. Credit: Margot Lepetit / Aalto University We all encounter gels in our daily lives, from the soft, sticky substances we put in your hair to jelly-like components of various food items. Human skin shares gel-like properties, but has unique qualities that are extremely difficult to replicate. It combines high stiffness…

Researchers develop highly robust, reconfigurable, mechanic cellulose photonic hydrogels
Graphical abstract. Credit: Today’s Material (2025). doi: 10.1016/j.mattod.2025.01.008 Inspired by natural boolean structures, researchers are developing advanced materials for impact-resistant bioforming, ceramic armors and biomimetic alloy composite applications. Most of the existing materials still consist of single-scale brittle units despite advances in improving material plasticity. The hierarchical active interface and lack of autonomous response capabilities limit its ductility and overall…

Conversion of marine waste and carbonated water into hydrogels by CO₂ emission behavior
Carbon dioxide creates the acidic environment necessary for calcium ions to bind alginate chains and form a hydrogel. However, the rapid release of CO2 after gelation limits the availability of calcium ions and reduces the cross-linking of alginate chains. Credit: Reprinted from Teshima et al. With permission from the Royal Society of Chemistry Hydrogels are soft materials made of cross-linked…

Utilizing exosomes and hydrogels to promote diabetic wound healing
Helical wheel diagram of the pentameric coiled coil and cartoon ribbon diagram of Q5 for reference. One helical wheel of Q5 is highlighted, with the corresponding helical wheel positions matching the residue positions (inside to outside) and starting from the partial heptad (VKE) starting from the e helical wheel position.
