Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Robust pH Sensing Using a Graphene Oxide and Covalent Organic Frameworks Composite for Gastro‐esophageal Reflux Disease Diagnosis

Advanced Healthcare Materials, EarlyView.
A stable composite pH sensor is developed by coating graphene oxide (GO) nanosheets with covalent organic frameworks (COFs) to improve stability and sensitivity in acidic environments. The GO/COFs sensor demonstrates high selectivity, linearity, and biocompatibility, offering a promising strategy for continuous pH monitoring in gastro‐esophageal reflux

Intermittent Catheters with Integrated Amphiphilic Surfactant Reduce Urethral Microtrauma in an Ex Vivo Model Compared with Polyvinylpyrrolidone-Coated Intermittent Catheters

Journal of Functional Biomaterials
Intermittent catheterization mitigates urinary retention for over 300,000 people in the US every year, but can cause microtrauma in the urothelium, compromising its barrier function and increasing the risk of pathogen entry, which may affect user health.

A Robust Heparin‐Mimicking Polyglycerol‐Based Coating for Blood‐Contacting Devices with Long‐Term Hemocompatibility and Preliminary Anti‐Inflammatory Properties

Advanced Healthcare Materials, EarlyView.
A robust heparin‐mimicking coating based on sulfated polyglycerol is constructed via layer‐by‐layer assembly on bloodcontacting surfaces. The coating exhibits long‐term anticoagulant and anti‐inflammatory properties by resisting protein adsorption, preventing platelet activation, and suppressing immune responses, offering a promising strategy for ...

Geometry‐Guided Osteogenesis in Bone‐on‐a‐Chip Systems Using Triply Periodic Minimal Surface Scaffolds

Advanced Healthcare Materials, EarlyView.
This study presents a bone‐on‐a‐chip platform incorporating TPMS scaffolds to study geometry‐dependent osteogenesis under dynamic flow. By tuning pore shape and solidity, it precisely controls mechanical cues, revealing how topological features and shear stress affect osteogenic differentiation and matrix formation.
