Tannic Acid‐Modified Cellulose Nanofiber Reinforced Polymerizable Eutectogels for High‐Performance Stretchable Strain Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A polymerizable deep eutectic solvent is reinforced with tannic acid‐modified cellulose nanofibers to construct a hierarchical dynamic eutectogel network. Synergistic covalent and reversible interactions impart ultrahigh stretchability, high ionic conductivity, broad temperature tolerance, self‐healing, and strong adhesion, enabling robust wearable ...

Enzyme‐Loaded Fe3+‐Modified Polydopamine Microparticles: Bioreactor Systems for Operating Biocatalytic Cascades, Enantioselective Transformations and Sensor Applications

open access: yesAdvanced Functional Materials, EarlyView.
Enzyme‐loaded Fe3+‐modified polydopamine microparticles (Fe3+‐PD) act as hybrid biocatalytic frameworks demonstrating NADH peroxidase‐mimic catalytic activities, operation of biocatalytic cascades in confined media, and enantioselective oxidation of D/L‐DOPA. ABSTRACT We report on the synthesis of Fe3+‐modified porous polydopamine microparticles acting

Mimetic Core‐Sheath Silk Sutures with Superior‐Strength for Pain Management, Anti‐Infection and Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...
