Iron–Copper Bimetallic Nanocomposite Reinforced Dressing Materials for Infection Control and Healing of Diabetic Wound

A multifunctional nanomaterial based wound healing matrix was fabricated by modified co-precipitation and chemical reduction method. The matrix was comprised of either a bimetallic Fe-Cu nanocomposite powder or a wound bed made up of absorbent cotton swab impregnated with bimetallic Fe-Cu nanocomposite. The detailed analytical studies of both dressing materials (powder and cotton bed) were carried out with transmission electron microscopy, X-ray diffraction, field emission scanning electron microscopy, energy-dispersive X-ray, and bright field microscopy. Both the nanocomposite powder and the nanocomposite impregnated cotton swab exhibited antimicrobial activity against Gram positive and Gram negative bacteria, including multidrug-resistant bacteria (such as methicillin-resistant
