Key Points

Synthesize iron oxide nanoparticle-decorated carbon nanotubes using pulsed laser ablation in liquid and evaluate their antimicrobial and wound-healing efficacy.
Synthesized iron oxide-decorated carbon nanotube nanocomposites using Nd:YAG-pulsed laser ablation in liquid.
Characterized nanomaterial structure and phase composition using transmission electron microscopy (TEM) and X-ray diffraction (XRD).
Evaluated antibacterial activity using nutrient broth and nutrient agar assays against diverse bacteria, followed by in vivo wound-healing assessments in animal models.
Transmission electron microscopy revealed semispherical iron oxide nanoparticles aggregating around rolled and unrolled graphene sheets, while X-ray diffraction confirmed carbon presence alongside distinct iron oxide phases.
Decorating carbon nanotubes with iron oxide nanoparticles produced enhanced antibacterial inhibition across broth and agar assays relative to non-composite controls.
Application of the optimal antibacterial nanocomposite concentration successfully promoted wound healing in animal models.

Implication

Preclinical study demonstrates enhanced antibacterial and wound-healing efficacy of iron oxide-decorated carbon nanotubes, indicating therapeutic potential for wound care.

Abstract

The antimicrobial activity was investigated for iron oxide IO nanoparticles (NPs)-decorated carbon nanotubes CNT prepared successfully by Nd:YAG-pulsed laser ablation in the liquid process. TEM reveals the composite NP and exhibits semispherical of iron oxide NPs, which aggregate around rolled and unrolled graphene sheet. XRD pattern proved the presence of carbon and different phases of IO NPs. Then, the antibacterial activity of the NPs was examined against different bacteria using nutrient broth and nutrient agar methods, which was enhanced using IO. In addition, the wound-healing activity for the best antibacterial concentration is tested by using animal models successfully.
