“…In turn, ZnO NPs synthesized from açaí seed residue extracts demonstrated broad antimicrobial activity against Gram-positive and Gram-negative bacteria, as published in our previous study [24]. This effect can be attributed to the large specific surface area and small particle size that allows them to passively pass through the bacterial cell wall and interact with intracellular components.…”

“…Other vibrations were observed in the regions between 1012 cm −1 and 1164 cm −1 , attributed to the C-O-C groups of polysaccharides [39]. Furthermore, the vibration range around 497 cm −1 is characteristic of the Zn-O bond of inorganic nanomaterial, as presented in our previous study [24].

In this work, novel nanocomposite films based on babassu coconut mesocarp and zinc oxide nanoparticles (ZnO NPs), synthesized by a green route, were produced for application as food packaging films. The films were prepared using the casting method containing different contents of ZnO NPs (0 wt%, 0.1 wt%, 0.5 wt%, and 1.0 wt%). The films were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), instrumental color analysis, and optical properties. The water vapor permeability (WVP) and tensile strength of films were also determined. The antimicrobial activity of the films against cooked turkey ham samples contaminated with Staphylococcus aureus was investigated. The results showed that incorporating ZnO NPs into babassu mesocarp matrices influenced the structure of the biopolymer chains and the color of the films. The BM/ZnO-0.5 film (0.5 wt% ZnO NPs) showed better thermal, mechanical, and WVP properties. Furthermore, the synergistic effect of babassu mesocarp and ZnO NPs in the BM/ZnO-0.5 film improved the antimicrobial properties of the material, reducing the microbial count of S. aureus in cooked turkey ham samples stored under refrigeration for 7 days. Thus, the films produced in this study showed promising antimicrobial packaging materials for processed foods.

Green synthesis techniques have recently become more popular due to the expanding interest in nanotechnology and the need for ecologically friendly synthesis processes. This work examines the environment friendly production of Zinc Oxide Nanoparticles (ZnO NPs) by a microwave-assisted technique, utilizing Pistia Stratiotes leaf extract as a reducing agent. The optical and structural properties of the produced ZnO NPs were analyzed using UV-Vis spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD). The findings indicated that the ZnO NPs displayed shapes consisting spherical, flower and sheet, with an average size of 35 nm which was verified by SEM and TEM. The XRD examination confirmed the presence of a hexagonal wurtzite crystalline structure, while the FTIR analysis identified a distinct peak at 578 cm-1, which indicates the stretching mode of Zn-O bonds. The antibacterial and antifungal properties of the substance were evaluated against Staphylococcus Aureus, Escherichia Coli, and Candida Albicans. The results demonstrated notable effectiveness, as indicated by inhibition zones measuring 16-20.4 mm, 17-21.3 mm, and 13-17.2 mm correspondingly. In addition, the ZnO NPs exhibited specific anti-cancer effects on SK-MEL-28 melanoma cell lines, with an IC50 value of 51.05 µg/ml, suggesting potential uses in therapy. This study demonstrates the feasibility of using microwave-assisted green synthesis to create ZnO NPs with favorable characteristics for biomedical purposes, with a particular focus on sustainable manufacturing of nanomaterials. The results indicate that these ZnO NPs show great potential for application in antibacterial, antifungal, and anticancer therapies, leading to developments in the field of medical nanotechnology.
