“…Chen et al reported the maximum absorbance peak of 360 nm in the UV spectrum of zinc oxide nanoparticles synthesized with Scutellaria baicalensis root extract (21). Hamk et al reported that the surface plasmon resonance peak of zinc oxide nanoparticles they synthesized with Bacillus subtilis supernatant was at 341 nm (22). In this study, the maximum absorbance peak of ZnONPs synthesized with Saccharomyces cerevisiae aqueous lysate was found to be 365 nm.…”

Objective: The aim of this study was to examine the toxic and wound-healing effects of Zinc oxide (ZnO) nanoparticles synthesized with an aqueous lysate of sourdough (Saccharomyces cerevisiae) on L929 mouse fibroblast cells. Methods: Zinc oxide nanoparticles were synthesized by microwave method using the aqueous lysate of Saccharomyces cerevisiae. Characterization of ZnO nanoparticles was carried out with Ultraviolet-Visible region spectroscopy (UV-Vis), SEM and Zeta sizer. The toxic behavior of ZnO nanoparticles and their effects on wound healing were investigated in vitro in L929 cells. Results: A sharp peak was observed at 360-380 nm specific to ZnO in the UV spectrum. In zeta analysis, the average size of ZnO nanoparticles was measured as 342 nm. The viability of L929 cells applied 1000 µg/mL ZnO was calculated as 90%. It was determined that the amount of wound closure of L929 cells applied 1000 µg/mL ZnO increased compared to the control group cells. Conclusions: In-vitro wound healing effects of Zinc oxide (ZnO) nanoparticles synthesized with Saccharomyces cerevisiae aqueous lysate show that these nanoparticles have the potential to be used in the pharmaceutical and cosmetic industries.

“…Notably, the crystallite size, as determined with XRD analysis, was found to be smaller than the particle size revealed through morphological examination. This suggests that the unique combination of biomolecules present in the Alazkher grass extract plays a pivotal role in achieving the distinctive nanoparticle shape observed in this study, setting it apart from other systems [ 54 ].…”

This study successfully synthesized zinc oxide nanorod needles (ZnO-NRNs) using an environmentally friendly method employing Cymbopogon Proximus extract. The resulting ZnO-NRNs exhibited exceptional physicochemical and structural properties, confirmed through various characterization techniques, including UV-Vis spectrophotometry, dynamic light scattering (DLS), transmission electron microscopy (TEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDX). The analysis revealed a hexagonal wurtzite structure with high crystallinity, a 3.6 eV band gap, and a notably blue-shifted absorption band. ZnO-NRNs showed impressive photocatalytic activity, degrading Rhodamine B dye by 97% under UV and visible sunlight, highlighting their photostability and reusability. This green synthesis process offers cost effectiveness and environmental sustainability for practical applications.

“…Another study used a hydrothermal technique to create ZnO@MnO 2 nanocomposites with sheet-like and nanorod morphologies of ZnO and MnO 2 nanostructures, respectively 76 . Finally, the size and shape of the resultant nanocomposite were influenced by the capping and reducing agents utilised, the synthesis method employed, or both 83 . The chemical compositions of myco-fabricated ZnO/MnO nanocomposite were further analyzed by EDX (Fig.…”

In this study, a ZnO/MnO nanocomposite was myco-fabricated using the isolated endophytic Clonostachys rosea strain EG99 as the nano-factory. The extract of strain EG99, a reducing/capping agent, was successfully titrated with equal quantities of Zn(NO3)2·6H2O and Mn(NO3)2·6H2O (precursors) in a single step to fabricate the rod-shaped ZnO/MnO nanocomposite of size 6.22 nm. The ZnO/MnO nanocomposite was myco-fabricated in 20 min, and the results were validated at 350 and 400 nm using UV–Vis spectroscopy. In a 7-L bioreactor, an industrial biotechnological approach was used to scale up the biomass of this strain, EG99, and the yield of the myco-fabricated ZnO/MnO nanocomposite. A controlled fed-batch fermentation system with a specific nitrogen/carbon ratio and an identical feeding schedule was used in this production process. Higher yields were obtained by adopting a controlled fed-batch fermentation approach in a 7-L bioreactor with a regular feeding schedule using a nitrogen/carbon ratio of 1:200. Overall, the fed-batch produced 89.2 g/l of biomass at its maximum, 2.44 times more than the batch's 36.51 g/l output. Furthermore, the fed-batch's maximum ZnO/MnO nanocomposite yield was 79.81 g/l, a noteworthy 14.5-fold increase over the batch's yield of 5.52 g/l. Finally, we designed an innovative approach to manage the growth of the endophytic strain EG99 using a controlled fed-batch fermentation mode, supporting the rapid, cheap and eco-friendly myco-fabrication of ZnO/MnO nanocomposite. At a dose of 210 µg/ml, the tested myco-fabricated ZnO/MnO nanocomposite exhibited the maximum antibacterial activity against Staphylococcus aureus (98.31 ± 0.8%), Escherichia coli (96.70 ± 3.29%), and Candida albicans (95.72 ± 0.95%). At the same dose, Staphylococcus aureus biofilm was eradicated in 48 h; however, Escherichia coli and Candida albicans biofilms needed 72 and 96 h, respectively. Our myco-fabricated ZnO/MnO nanocomposite showed strong and highly selective antagonistic effects against a variety of multidrug-resistant human pathogens. Therefore, in upcoming generations of antibiotics, it might be employed as a nano-antibiotic.
