Green nanotechnology advances: green manufacturing of zinc nanoparticles, characterization, and foliar application on wheat and antibacterial characteristics using Mentha spicata (mint) and Ocimum basilicum (basil) leaf extracts

Environ Sci Pollut Res Int. 2023 Apr 11. doi: 10.1007/s11356-023-26827-3. Online ahead of print.ABSTRACTDue to their distinctive characteristics and widespread application across all scientific disciplines, nanoparticles have attracted a lot of attention in the current millennium. Green synthesis of ZnO-NPs is gaining a lot of interest at the moment due to a number of its advantages over traditional methods, including being quicker, less expensive, and more environmentally friendly. In the current study, two distinct plant extracts are used to quickly, cheaply, and environmentally friendly synthesize zinc oxide nanoparticles (ZnO-NPs). Mint (Mentha spicata) and basil (Ocimum basilicum) were the plants employed in this study as stabilizing agents to synthesize ZnO-NPs with a green chemistry approach. The innovative aspect of the study is the use of mint and basil extracts in the conversion of zinc chloride to zinc oxide and then determining the effect of these two types of nanoparticles produced by green synthesis on the growth parameters of the plant when they reach the plants by foliar spraying and their uptake by plants and evaluating the antibacterial properties of these nanoparticles. The physical properties of the produced nanoparticles were investigated using XRD, SEM, and FTIR. Moreover, Escherichia coli and Staphylococcus aureus were used to demonstrate the antibacterial properties of ZnO-NPs against both gram-positive and gram-negative bacteria, respectively. Synthes...
