An Ionic Gelation Powder for Ultrafast Hemostasis and Accelerated Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
An ultrafast ionic gelation‐activated hemostatic powder (AGCL) forms a hydrogel within ≈1 s upon contact with blood‐derived calcium ions. The AGCL powder enables rapid hemorrhage control, strong tissue adhesion, and enhanced healing. The powder's pre‐crosslinked polymer network ensures high blood uptake and stability, offering effective treatment for ...

Nitric Oxide‐Releasing Catheters with Phenol‐Amine Catalytic Coatings for Improved Anti‐Inflammatory Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Tannic acid‐selenocystamine (TA‐SeCA) nanocoating enables stable, sustained catalytic nitric oxide (NO) release on catheter surfaces. This one‐step phenol‐amine coating improves catheter functionality by enhancing endogenous NO production, supporting vascular function, and reducing inflammation.

A Computational Journey Toward an Optimal Design for Metamaterial Epicardial Passive Sleeves

open access: yesAdvanced Healthcare Materials, EarlyView.
Passive epicardial sleeves are evaluated in 3D in‐silico heart models to reveal how sleeve geometry, stiffness, anisotropy, and metamaterial architecture influence cardiac mechanics after myocardial infarction. A continuum‐to‐auxetic design exploration shows that region‐specific mechanical engagement can reduce infarct bulging and modulate torsional ...
