Influence of Silver Nanoferrite and Nanochromite on Physical Properties for High-Frequency and Biomedical Applications

Abstract

AbstractIn this work, the effects of silver nanoferrite and nanochromite (Ag2Fe2O2, Ag2Cr2O4) were studied using the flash auto-combustion technique. Numerous physical properties were clarified from the different structures determined from the x-ray examination such as lattice parameter the cation dispersion, oxygen parameter, hopping length, and interatomic distance. Among antimicrobial properties, Ag addition to both samples showed high efficacy against both types of tested bacteria (gram-positive and gram-negative); however, they showed moderate effect against Candida albicans fungus. No activity appeared against Aspergillus flavus fungus for both samples. The switching field and high-frequency response of Ag2Fe2O4 and Ag2Cr2O4 nanoparticles were studied from the magnetic properties. Ag2Cr2O4 nanoparticles are expected to be used for high-frequency applications more than Ag2Fe2O4 ones. As a result of all previous analyses, the applications of this study promote the use of Ag2Fe2O4 nanoferrite and Ag2Cr2O4 nanochromite for high-frequency, switching field, and biomedical applications as antimicrobial nanomaterials.
