The Effect of Hydrothermal Reaction Time on the Antibacterial Activity of Synthesized Manganese Oxide Nanoparticles
J. Environ. Nanotechnol., Volume 12, No 4 (2023) pp. 87-92
Abstract
In the context of growing antibiotic resistance and the associated side effects of traditional antibiotics, this research explores the use of nanosized manganese oxide (Mn3O4) as a novel antibacterial agent. This study pioneers the synthesis of Mn3O4 through an eco-friendly hydrothermal method, varying reaction times (2, 4 and 6 hours) at a consistent temperature of 180 °C. Characterization techniques, including X-ray diffraction, Fourier-transform infrared spectroscopy and Scanning electron microscopy, provide insights into their crystallinity, functional groups and morphology. The synthesized Mn3O4 demonstrates remarkable antibacterial efficacy, with larger inhibition zones against both Gram-positive and Gram-negative strains compared to standard antibiotics. This research presents the synthesizing of an eco-friendly, cost-effective antibacterial agent through a straightforward hydrothermal method. Varying reaction times unveil distinctive antibacterial capabilities, making Mn3O4 a promising candidate for future antimicrobial systems and medical applications.
