Özet:

notechnology is relatively new branch of science and technology with many interesting applications. This technology involves in the synthesis of inorganic nanoparticles (NPs) through green synthesis using extracts of plant-derived materials. Green synthesis of metal and metal oxide NPs is a good alternative over the other conventional physical and chemical methods. This study deals with the green synthesis of manganese oxide (MnO2) NPs using the extract of Aloe vera. The green synthesized MnO2 NPs have been synthesized using various analytical methods such as Fourier transform infrared, X-ray diffraction, and field emission scanning electron microscope. MnO2 NPs were tested for antibacterial activities against Escherichia coli, Streptococcus mutans, and Staphylococcus aureus using well diffusion method. The experimental results were indicating that the MnO2 NPs are good antibacterial agents against different bacterial species.
