Background This study aimed to environmentally synthesize zinc oxide nanoparticles (ZnO-NPs) using (AC) extract and evaluated their antimicrobial efficacy against , , and . Methodology AC extract was combined with a zinc sulfate solution to synthesize ZnO-NPs. The NPs were characterized using UV-visible spectroscopy, Fourier transform infrared (FTIR) analysis, scanning electron microscopy (SEM), and energy-dispersive electron microscopy (EDX). Antimicrobial activity was assessed using the agar disc diffusion method against , , and . Results Green synthesis of ZnO-NPs with AC extract yielded NPs of different sizes and shapes. SEM analysis showed circular and conical NPs measuring up to 10 nm. EDX analysis confirmed the presence of zinc (Zn) and oxygen (O) particles. UV-visible spectroscopy indicated ZnO-NP formation with a peak at 290 nm. These NPs exhibited strong antimicrobial activity against , with larger inhibition zones at higher concentrations, i.e., 15 mm at 100 μL. Whereas they showed low activity of 12 mm at 100 μL against and showed no activity against . Conclusions Environmentally friendly synthesis of ZnO-NPs using AC extract provides an effective method for NP production. It exhibits strong antimicrobial activity against , indicating the potential for targeted antimicrobial solutions in addressing associated infections.

Introduction: Zinc oxide nanoparticles (ZnO NPs) exhibit a wide range of biomedical applications majorly used as antiinflammatory, anti-cancer, anti-diabetic, and anti-microbial activity and other biomedical applications because they show less toxicity and are very compatible. Zinc metal is an inorganic and essential element in the human body at the trace level. ZnO NPs are also GRAS substances (Generally Recognized As Safe).

Article Synopsis
- This study compares the behavior of two plant species and their extracts in synthesizing zinc oxide nanoparticles from zinc nitrate hexahydrate.
- Sugars, particularly glucose and sucrose, play a crucial role in this synthesis, comprising over 70% of the dried extract.
- The process can successfully occur at low temperatures (120°C) but requires a specific ratio of reactants to ensure the production of "clean" ZnO nanoparticles.

Extracts of medicinal seeds can be used to synthesize nanoparticles (NPs) in more environmentally friendly ways than physical or chemical ways. For the first time, aqueous extract from unexploited grape seeds was used in this study to create Se/ZnO NPS utilizing a green technique, and their antimicrobial activity, cytotoxicity, antioxidant activities, and plant bio stimulant properties of the economic Vicia faba L. plant were evaluated.

In this study, biopolymer of chitosan-based films were synthesized, which were impregnated with zinc oxide nanoparticles (ZnO NPs) at concentrations of 0, 1, 5 and 10 % w:v to obtain a film with microbicide properties and non-toxic for humans. The ZnO NPs were phytosynthesized with ethanolic extract of Ruta graveolens, by UV-Vis spectrophotometry and Tauc equation were estimated their Band gap energy=3.37 eV at wavelength of 302 nm.
