Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

open access: yesAdvanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

Fibrous Pressure Sensor with Unique Resistance Increase under Partial Compression: Coaxial Wet‐Spun TiO2/Graphene/Thermoplastic Polyurethane Multi‐Wall Multifunctional Fiber

open access: yesAdvanced Materials, EarlyView.
TGTMW fibers are designed to show a sharp resistance increase under pressure, as the multi‐wall structure in the transition region between compressed and uncompressed areas bends and forms microcracks. This design breaks the physical sensitivity limit of conventional fiber‐shaped pressure sensors, which usually show resistance reduction under pressure ...

A Hydro‐Expansive and Degradable Biomaterial Enabling Shape Recovery of Film‐Based Devices in Biofluids

open access: yesAdvanced Materials, EarlyView.
A chitosan‐based bio‐composite exhibits stable and strong tensile strength during volumetric expansion in body fluids, serving as a functional coating that enables a thin film‐based device to self‐flatten from its tubular shape required for catheter delivery.

Exploring the Role of Stent Strut Geometry in Cellular Behavior: An In Vitro Chip Model to Understand In‐Stent Restenosis

open access: yesAdvanced Materials Interfaces, EarlyView.
An engineered in vitro platform mimicking stent strut cross‐sectional shapes reveals how geometry influences cell behavior. Sharp‐cornered geometries promote cell proliferation and matrix alignment, while rounded shapes reduce these effects. The findings align with clinical outcomes and suggest intracellular tension as a key driver, offering a ...

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...
