Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Hierarchical Cellulose/MXene Aerogel Films with Coral‐Like Polyaniline Skin for Absorption‐Led Broadband EMI Shielding

open access: yesAdvanced Functional Materials, EarlyView.
A regenerated cellulose/MXene aerogel film is engineered with a surface‐confined, coral‐like polyaniline skin to intensify interfacial polarization while a porous, percolated conductive core is retained. By molten salt hydrate processing and interfacially confined oxidative polymerization, PANI growth is localized at the outer surface and internal ...

Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

open access: yesAdvanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Membrane Vesicles from Lacticaseibacillus Casei BL23 Exhibit Antimicrobial Activity Against Escherichia coli and Immunostimulatory Effects on Human Peripheral Blood Mononuclear Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...
