Moringa Oleifera leaf-based zinc oxide nanoparticles: Green synthesis, characterization, and their antibacterial investigations

[Display omitted] •This paper investigates green synthesis as a strategic and environmentally friendly method of synthesizing effective ZnO nanoparticles.•Although natural and eco-friendly antibacterial agents and substitutes are making their way into the market, there is a lack of eco-friendly zinc oxide nanoparticles derived from moringa that may be used in personal hygiene products and have proven to be effective.•The anti-bacterial biological activity is performed.•The minimum inhibitory concentration MOL: ZnO NPs added benefits of moringa phytochemicals and is an excellent approach to developing eco-friendly and multifunctional versatile products having strong antioxidants, anti-acne and advanced antibacterial efficacy for numerous industrial applications like cosmetic, health hygiene products, drugs, therapeutic, food packing and advanced forensic applications. In the current study, an extract from Moringa Oleifera (MO) leaves was utilized for synthesis nanoparticles (ZnO) in an easy-to-use and ecologically friendly manner. Different ratios of MO leaf extraction (1:1, 1:3, 1:5, and 1:7, 1:9) were used to synthesize the nanostructured ZnO. The synthesized ZnO NPs were examined using an array of analytical methods, including energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV–Vis absorption spectroscopy, and antibacterial investigations. The synthesized MOL: ZnO NPs confirmed the hexagonal wurtzite structure, as demonstrated by XRD analysis. FT-IR demonstrated that the presence of distinct functional groups was required for the reduction of the metal ion into MOL: ZnO NPs. High purity and crystalline EDX has been used to identify the intense and narrow measurements of the zinc and oxygen found in the MOL: ZnO NPs. After being examined for antibacterial activity, the produced MOL: ZnO NPs showed the highest zones of inhibition against both gram negative Pseudomonas and gram positive Bacillus. The results show that ZnO-based NPs aided by leaf extract of Moringa Oleifera are the promising materials for a variety of applications such as food package applications and advanced forensic applications.
