Vegetable Peel Waste for the Production of ZnO Nanoparticles and its Toxicological Efficiency, Antifungal, Hemolytic, and Antibacterial Activities

Abstract

Zinc oxide (ZnO) nanoparticles (NPs) are important materials when making different products like sun screens, textiles, and paints. In the current study, the photocatalytic effect of prepared ZnO NPs from Moringa oleifera (M. oleifera) was evaluated on degradation of crystal violet (CV) dye, which is largely released from textile industries and is harmful to the environment. Preliminarily, ZnO NP formation was confirmed using a double beam ultraviolet visible (UV-Vis) spectrophotometer; further, the NP size was estimated using XRD analysis and the functional group analysis was determined using Fourier transform infrared (FT-IR) spectroscopy. The morphology of the synthesized NPs was found to be a hexagonal shape using SEM and TEM analysis and elemental screening was analyzed using EDX. ZnO NPs were shown sized 40–45 nm and spherical in shape. The degradation percentage of ZnO NPs was calculated as 94% at 70 min and the rate of the reaction –k = 0.0282. The synthesized ZnO NPs were determined for effectiveness on biological activities such as antifungal, hemolytic, and antibacterial activity. ZnO NPs showed good antifungal activity against Alternaria saloni and Sclerrotium rolfii strains. Further, we have determined the hemolytic and antibacterial activity of ZnO NPs and we got successive results in antibacterial and hemolytic activities.

<p>Comparison of cytocompatibility and anticancer properties of traditional and green chemistry-synthesized tellurium nanowires</p>

“…Green chemistry approaches are especially useful for the generation of metallic nanoparticles (NPs), which have nanometric structures that effectively and efficiently address concerns in both health care and industrial applications. [33][34][35] Therefore, these approaches offer the chance to use living organisms (such as bacteria, 36 human cells, 37,38 fungi, 39 or plants 40,41 ) as well as dietary and organic natural compounds (such as coffee, 42 tea, or honey extracts 43 ) or biological waste materials produced from industrial alimentary plants, 44 to naturally synthesize NPs. These nanostructures exhibit antibacterial and/or anticancer properties and can be used as drug delivery carriers and in industrial applications.…”

An Efficient Approach for the Synthesis of 1,1‐bis(2‐phenyl‐3‐indolyl)ethylene Using ZnO Nanocatalyst

“…The recent literature survey revealed that ZnO nanoparticles as heterogenous catalyst as received much attention due to the advantages: that is, minimum execution time, easy workup procedure, low corrosion, economically cheap chemical, commercially available, easily synthesized , and recycling of it. In recent years, ZnO nanoparticles have excellent potential in expressing abundant biological properties such as antimicrobial , antioxidant, anticancer, and other activities . ZnO nanoparticles were also suggested as good photocatalytic agents .…”
