Hydrogels: From Simple Covalently Cross‐Linked Systems toward Hydrophobically Associating Adaptive Semicrystalline Materials

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
The exceptional toughness of these hydrogels originates from a lamellar cluster structure in which tie molecules, formed by PDMAAm chains containing noncrystallized C18A and C12M segments, transfer stress, and dissipate energy during deformation. Fragmentation of lamellar clusters under load produces yielding, whereas hydrogels without C12M lack this ...

Multi‐Responsive PAA/PNIPAM Semi‐IPN Hydrogel Properties Controlled by PAA Topology

open access: yesMacromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Polymer topology governs hydrogel behavior in semi‐interpenetrating networks. Cyclic poly(acrylic acid) enables controlled pH‐responsive swelling, improved stability, and enhanced deformability compared to linear analogues, while linear systems show higher strength during thermal de‐swelling.

Injectable Artificial Photoreceptors: STEM Cell Functional Integration and in vivo Electrophysiological Validation in Retinal Degeneration Models

open access: yesSmall Science, Volume 6, Issue 8, August 2026.
Artificial photoreceptors are engineered to efficiently absorb light, with the strongest sensitivity in the green region of the visible spectrum. Upon illumination, they generate electrical signals that activate retinal ganglion cells, which are typically unaffected by disease, enabling transmission of visual information to the brain.
