AbstractAluminum oxide, often known as Al2O3, is a chemical compound of aluminum and oxygen with the formula Al2O3. It's the most common of many aluminum oxides, known as aluminum (III) oxide. The study investigates the cytotoxicity and antibacterial effects of Aluminum oxide nanoparticles (Al2O3-NPs) in different cells and bacteria. Different characterization methods such as dynamic light scattering (DLS), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) have been used to evaluate morphologies and physicochemical properties of Al2O3-NPs. MTT technique is used for determining NPs cytotoxicity. The size distribution of Al2O3-NPs was 68 ± 12 nm in diameter, while the zeta potential was (-36 ± 10 mV). There is no toxicity by using the MTT assay, as well as showed antibacterial activity was formed at 200 µg/mL, while the higher antibacterial activity was occurring at (18 ± 0.2) and (17 ± 0.1) for Proteus Vulgaris and Streptococcus pyogenes, respectively. The findings confirmed that the Al2O3-NPs have small dimensions, high stability, and increased antibacterial activity.
