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

ABSTRACT: This study introduces an innovative design and application of a nitrogen-interstitially strengthened Cu-Fe-Zn alloy bioactive dressing, which combines intrinsic bioactivity with electromagnetic stimulation to significantly accelerate wound healing. Interstitial nitrogen solid-solution Cu-Fe-Zn alloys were fabricated by integrating a low-oxygen controlled powder sintering process (N2(10%)/Ar (90%) atmosphere). Subsequent cold drawing generated ultrafine alloy wires (0.04 ± 0.005 mm) with a tensile strength of 1120 MPa, representing a 20.37% enhancement compared with conventional approaches. Utilizing an intelligent jacquard textile system, these Cu-Fe-Zn alloy wires and cotton yarn were woven into coaxial circular dressings tailored to wound morphology, allowing controlled directional curre
