Study of biocompatibility and wound healing properties of strontium hexaferrite (SrFe12O19) nanoparticles

Strontium hexaferrite nanoparticles were prepared using the sol–gel auto-combustion method. Their magnetic and structural properties were carefully studied. X-ray diffraction (XRD) confirmed that the material had a pure phase, while field emission scanning electron microscopy (FESEM) was used to observe the surface structure. The elements present in the material were identified using energy-dispersive X-ray spectroscopy (EDX). Magnetic properties were analyzed with a vibrating sample magnetometer (VSM). Lab tests at various concentrations showed that the nanoparticles had antibacterial effects. Cytotoxicity tests also confirmed that they are safe for biological use, suggesting they could be useful for wound healing.
