“…Moreover, MgO NPs have improved optical and UV-shielding properties . MgO NPs are easily reachable and Generally Recognized As Safe (GRAS), permitted by the Food and Drug Administration (FDA) . Because of these features, MgO NPs have been considerably used in numerous applications like food packaging, cosmetics, pharmaceuticals, electronic devices, dye degradation, and biosensors. , MgO NPs, as a transition-metal oxide, are infrequently employed as sensing materials, owing to their higher band gap, which makes charge carrier generation more challenging.…”

Fabricating active and intelligent packaging materials has become the highest demand for catering to market needs, especially after the COVID-19 pandemic, for ensuring food safety. Thus, the wider objective of this article was to promote active and smart packaging biofilms possessing antibacterial and humidity-sensing properties for sustainable poly(vinyl alcohol) (PVA)/gelatin (Ge) reinforced with biosynthesized magnesium nanoparticles (MgO NPs) by a solvent-casting route. The UV−visible spectrum has been utilized to determine the optimized biosynthesized MgO NPs and then the nanostructure of optimized MgO NPs investigated by varying techniques such as XRD, SEM−EDX, TEM, FT-IR, and thermogravimetric analysis. Four MgO NPs proportions (i.e., 1, 3, 5, and 10 wt %) were used to fabricate PVA/Ge biofilms. In the biofilms system, the tensile results showcased that the nanocomposite film containing 5 wt % of MgO NPs had the highest tensile strength value (i.e., 22.10 MPs) compared to the other biofilms or the unfilled blank (i.e., 6.30 MPs). Correspondingly, the humidity-sensing data revealed that the PVA/Ge-1% MgO NPs sensor had higher sensitivity over a broad range of relative humidity from (7−97% RH) and at 100 Hz. Additionally, the hydrophobicity of biofilms, measured by water contact angle, UV-stability, and antioxidant and antibacterial properties was also analyzed to possibly use these biofilms in active food packaging with extended shelf life of foodstuffs. However, the PVA/Ge-1% MgO NPs biofilm was predominately found to possess attractive sensing properties and could be considered as a sensor for intelligent food packaging.

“…Zinc oxide nanoparticles, on the other hand, were approved by FDA as GRAS materials. It is also used as an additive in animal feed like fish and pigs [ 5 ]. Fortunately, the physical processes of blocking virus attachment, infection, and uncoating have been identified as the mechanisms by which zinc-containing drugs exert their antiviral effects against various viruses.…”

Almost one-third of all infectious diseases are caused by viruses, and these diseases account for nearly 20% of all deaths globally. It is becoming increasingly clear that highly contagious viral infections pose a significant threat to global health and economy around the world. The need for innovative, affordable, and safe antiviral therapies is a must. Zinc oxide nanoparticles are novel materials of low toxicity and low cost and are known for their antiviral activity. The genus Pelargonium was previously reported for its antiviral and antimicrobial activity. In this work, Pelargonium zonale leaf extract chemical profile was studied via high-performance liquid chromatography (HPLC) and was used for the biosynthesis of zinc oxide nanoparticles. Furthermore, the antiviral activity of the combination of P. zonale extract and the biosynthesized nanoparticles of ZnO against the human corona 229E virus was investigated. Results revealed that ZnONPs had been biosynthesized with an average particle size of about 5.5 nm and characterized with UV, FTIR, TEM, XRD, and SEM. The antiviral activity showed significant activity and differences among the tested samples in favor of the combination of P. zonale extract and ZnONPs (ZnONPs/Ex). The lowest IC50, 2.028 µg/mL, and the highest SI, 68.4 of ZnONPs/Ex, assert the highest antiviral activity of the combination against human coronavirus (229E).

“…The latter have the advantage of being able to be synthesized at temperatures lower than 350 degrees Celsius [11].Biological methods rely on microorganisms such as plant extracts, bacteria, yeasts, and fungi to produce nanoparticles [12][13]. These methods have the advantages of being easily scaled, non-toxic, environmentally friendly, and reproducible [14]. As a result of global development, favouring good health and mitigating disease risk, the trend toward natural products has gained widespread attention.…”

Zeolitic imidazolate framework-8 (ZIF-8) is regarded in this study as a simple and lowcost alternative catalyst for the isomerization of glucose and the production of 5-hydroxymethyl furfural (HMF). Two methods of preparing ZIF-8 catalysts were investigated: room temperature and hydrothermal synthesis at 140 °C. The hydrothermal synthesis method yields a material with a very large surface area (1967 m 2 g -1 ). When used as a catalyst, the ZIF-8 materials produced excellent fructose yields. ZIF-8 prepared by hydrothermal synthesis had a fructose selectivity of 65% and a glucose conversion of 24% at 100 °C in aqueous reaction medium. The selectivity dropped dramatically when the reactions were repeated at higher temperatures (140 °C). Surprisingly, higher temperatures resulted in higher levels of mannose production. Due to a lack of strong Brnsted acidity, ZIF-8 materials had low HMF yields. Despite the excellent performance of ZIF-8 catalysts in batch reactions, their activity did not translate well to the flow reactor during an 8-hour continuous run with a residence time of 6 minutes. The activity of ZIF-8 in the flow reactor at 100 °C was halved in 3 hours, implying that the catalyst's stability was not maintained in the long run.
