Fabrication of ultrasound-mediated cerium oxide nanoparticles for the examinations of human osteomyelitis and antibacterial activity

In this work, two Gram-negative and three Gram-positive pathogenic pathogens were examined for the antibacterial activity of cerium oxide nanoparticles. CeO 2 nanoparticles (CeO 2 NPs) encapsulation with hydroxyapatite and chitosan were synthesised using the precipitation procedure and simultaneous reactant addition by techniques of a Wet Chemical Synthesis approach. Thermal analyses (TG–DTA), their degradation processes and their synthesis of CeO 2 NPs were investigated, and the precursor powders were acquired. Fourier transform infrared (FTIR), X-ray diffraction, Raman spectroscopy, transmission electron microscopy (TEM), and dynamic light scattering (DLS) examined the thermally treated sample’s composition, structure, and morphology. CeO 2 NPs antioxidant has also been determined. The analysis against five diseased pathogens, including Bacillus cereus, Staphylococcus aureus , Listeria monocytogenes , Salmonella typhimurium and Escherichia coli , has been performed on both fluid growth mediums. The growth inhibition of cerium oxide nanoparticles in all five pathogens studied exhibited noteworthy results. This study underlines the CeO 2 NPs, which revealed considerable changes in antibacterial activity because of the changes in membrane structure and the composition of cell walls across the two test groups. As a result, generated CeO 2 NPs can be prospective osteomyelitis therapy candidates.
