“…Because of environmental toxicity and pollution, many researchers have suggested the green synthesis route for the synthesis of ZnO NPs from cheap natural biowastes or agricultural wastes, such as leaf, flower, and seed. [2,15,16] Many studies have indicated that plant extracts could act as a reducing, capping, and stabilizing agent during the production of metallic NPs at ambient conditions due to their simplicity and costeffectiveness. [17] The agrowastes contain secondary metabolites and reduce metal ions by bioactive compounds present in them, such as enzymes, phenolic and flavonoid compounds, vitamins, and amino acids.…”

“…Recently, many studies have focused on nanoparticles (NPs) due to their very small size with large surface‐to‐volume ratio that confers them unique beneficial properties. [ 1–4 ] In this regard, metal NPs have gained considerable interest because of their outstanding physicochemical properties including thermal and electrical conductivity, anticancer and antimicrobial activities, and ability to degrade pollutants (dyes and toxins), compared with their bulk counterparts. [ 5 ] Zinc oxide (ZnO) NPs is a type of metal oxide NP that is recognized as a multifunctional, nontoxic, and biocompatible inorganic material [ 6 ] with many applications in food packaging materials, [ 7 ] sunscreens, paints and coatings (as they provide high UV protection), [ 8 ] optics, optoelectronics, [ 9 ] and elimination of heavy metals from water.…”

To increase the profitability and sustainability of agricultural waste, a facile green approach was established to synthesize zinc oxide nanoparticles (ZnO NPs) using saffron leaf extract as a reducing and stabilizing agent. Structural characteristics of NPs were investigated by X-ray diffraction (XRD), Fouriertransform infrared (FTIR), field emission scanning electron microscopy (FESEM), and UV-Visible (UV-Vis) spectroscopy. Characterization results revealed that ZnO NPs is highly crystalline with a hexagonal wurtzite structure and spherical particles with diameter less than 50 nm, as confirmed by XRD and FESEM techniques. UV-Vis absorption spectra depicted an absorption peak at 370 nm, which confirms the formation of ZnO NPs. FTIR spectral analysis confirmed the presence of functional groups and metal oxygen groups. The biological activities of ZnO NPs were also investigated. The antibacterial effect of ZnO NPs was investigated against selected food pathogens (Salmonella Typhimurium, Listeria monocytogenes, and Enterococcus faecalis). The study results prove that the green synthesized ZnO NPs show enhanced antibacterial activity against S. Typhimurium when compared with other strains. A dose-dependent free radical scavenging activity was observed for ZnO NPs in both 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and fluorescence recovery after photobleaching (FRAP) assays. The ZnO NPs were evaluated for their photocatalytic activity during the degradation of methylene blue (MB) dye in aqueous solutions. The maximum removal of MB achieved was 64% with an initial ZnO NP concentration of 12 mg/mL under UV light. The present study revealed that the agricultural waste (saffron leaf) provides a simple and eco-friendly option to sustainably synthesize ZnO NPs for use as a photocatalyst. In addition, this is the first report on saffron leaf-mediated synthesis of ZnO NPs.

The versatile application of metal‐based nanoparticles has led to a recent rise in interest in the low‐cost and eco‐friendly green chemistry‐based development of metal oxide nanoparticles. This work focuses on the photocatalytic and antibacterial uses of the zinc oxide nanoparticles (ZnONPs) that were produced based on a green approach employing stem extract of Piper chaba. The formation of ZnONPs was preliminary validated by the appearance of an absorption band at 373 nm and a stretching band due to ZnO at 480 cm−1 in UV–Vis and FTIR spectrum, respectively. The crystalline nature of ZnONPs with a hexagonal wurtzite phase and an average crystallite size of 25 nm was validated by XRD analysis. ZnONPs' crystalline nature was further supported by TEM, which further showed that they were mostly cubic in form and had an average length of 30 nm. Synthesized ZnONPs demonstrated significant antibacterial activity against Salmonella typhi, Vibrio cholerae, Escherichia coli, and Staphylococcus aureus and lucrative photocatalytic activity with the rate constant value of 0.0273 min−1 towards the degradation of methylene blue under sunlight exposure. Therefore, a facile, affordable, and ecologically sustainable method like this might be used for the large‐scale synthesis of ZnONPs.

In the present work, a green method improved by surface response methodology (SRM) has been used for the synthesis of zinc oxide nanoparticles (ZnONPs) from coffee husks extract, in which Santa Barbara‐15 (SBA‐15) mesoporous silica has been embedded. The composite formed has been drop coated on bare glassy carbon electrode and the resulting sensor (ZnONPs/SBA‐15/GCE) was used for the sensing of acetaminophen (ACT). Reaction factors such as pH, incubation time and precursor concentration were optimized during nanoparticles synthesis using SRM. The synthesized nanoparticles and the composite were characterized by ultraviolet‐visible spectrophotometry (UV‐Vis), Fourier transform infrared (FTIR) spectroscopy, powder X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X‐ray (EDX/EDX‐mapping) analysis, thermogravimetry analysis/differential thermogravimetry (TGA/DTG), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS), showing the good elaboration of ZnONPs/SBA‐15/GCE. After optimization of parameters susceptible to affect the detection limit of ACT, the calibration curve was plotted from 4 μM to 32 μM, showing good linear response with a detection limit of 0.11 μM. The developed sensor shows good sensitivity, reproducibility, repeatability and storage stability at room temperature and was successfully applied for the determination of ACT in pharmaceutical sample.
