Assessment of the antibacterial efficacy of nickel/manganese nanoparticles against staphylococcus aureus

Nickel/Manganese nanoparticles were assessed as an antibacterial agent in the current investigation. Atomic force microscopy and absorption spectroscopy means were used for scanning electron microscopy and Fourier-transform infrared spectroscopy analysis. The nickel/manganese oxide nanoparticles were created by using leaf extract from Lepidium sativum. These nanoparticles were ultimately described using diffraction patterns of X-rays. Two different concentrations were created from the synthesized Nickel/Manganese nanoparticles, and their potential antibacterial action towards Staphylococcus aureus was examined. The test results showed that the nanoparticles are spherical, either by themselves or grouped together, and solid for Nickel/Manganese. Their average size is 45.9 nm. Nickel/Manganese nanoparticles restrict bacterial proliferation, as demonstrated by extensive inhibition zones against S. aureus across all tested doses. Moreover, the minimum inhibitory concentration values of Nickel/Manganese nanoparticles against S. aureus isolates No. 2, 5, 6, 7, and 10 were (1 mg/ml), while isolates No. 1, 3, 8, and 9 exhibited minimum inhibitory concentration values of (2 mg/ml), and isolate No. 4 demonstrated a minimum inhibitory concentration of 4 mg/ml. The action against biofilms of Nickel/Manganese nanoparticles in opposition to S. aureus isolates shown inhibition of 80% at (0.5 mg.ml−1), 100% at (1 mg.ml−1) in biofilm formation.
