Abstract

Green nanotechnology 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.

Summary

Introduction

The nano-based materials have been used for efficiency, durability, and effectiveness. Such materials are commonly used in biological, physical, chemical, pharmaceutical, engineering, and environmental sciences due to improved surface area to volume ratio.[1] The nano-based materials or nanoparticles (NPs) can be synthesized using different physical and chemical methods. The plant extract-based synthesis of inorganic NPs is highly efficient, low cost, and nontoxic. MnO2 NPs are used in sensors, energy storage, catalysis, environmental remediation, and antimicrobial activities.[4,5,6,7,8,9] In this study, we have synthesized MnO2 NPs using the extract of Aloe vera plant.
