Interstitial N‐Strengthened Copper‐Based Bioactive Conductive Dressings Combined with Electromagnetic Fields for Enhanced Wound Healing

Advanced Healthcare Materials, EarlyView.
This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...

Biphasic Granular Bioinks for Biofabrication of High Cell Density Constructs for Dermal Regeneration

Advanced Healthcare Materials, EarlyView.
This study introduces a biphasic granular bioink (µInk) that enables 3D bioprinting of high cell density constructs for dermal regeneration. The bioink promotes cell proliferation, ECM deposition, and neovascularization, leading to tissue integration and reduced scar formation in vivo.
