“…Over the years, various antimicrobial agents have been investigated to inhibit microbial growth in diverse fields such as agriculture, medicine, and food packaging. These include inorganic antimicrobial agents (Park et al., 2023; Puangsin et al., 2022; Wang et al., 2022; Zhang, Li et al., 2023) (metallic compounds and nanoparticles) and organic antimicrobial agents (Li, Chen et al., 2021; Liu et al., 2023; Nian et al., 2023) (quaternary ammonium compounds, chitosan, and plant extracts). Figure 1 illustrates common antimicrobial substances, detailing their mechanisms of action and application domains.…”

The environmental challenges posed by plastic pollution have prompted the exploration of eco‐friendly alternatives to disposable plastic packaging and utensils. Paper‐based materials, derived from renewable resources such as wood pulp, non‐wood pulp (bamboo pulp, straw pulp, reed pulp, etc.), and recycled paper fibers, are distinguished by their recyclability and biodegradability, making them promising substitutes in the field of plastic food packaging. Despite their merits, challenges like porosity, hydrophilicity, limited barrier properties, and a lack of functionality have restricted their packaging potential. To address these constraints, researchers have introduced antimicrobial agents, hydrophobic substances, and other functional components to improve both physical and functional properties. This enhancement has resulted in notable improvements in food preservation outcomes in real‐world scenarios. This paper offers a comprehensive review of recent progress in hydrophobic antimicrobial paper‐based materials. In addition to outlining the characteristics and functions of commonly used antimicrobial substances in food packaging, it consolidates the current research landscape and preparation techniques for hydrophobic paper. Furthermore, the paper explores the practical applications of hydrophobic antimicrobial paper‐based materials in agricultural produce, meat, and seafood, as well as ready‐to‐eat food packaging. Finally, challenges in production, application, and recycling processes are outlined to ensure safety and efficacy, and prospects for the future development of antimicrobial hydrophobic paper‐based materials are discussed. Overall, the emergence of hydrophobic antimicrobial paper‐based materials stands out as a robust alternative to plastic food packaging, offering a compelling solution with superior food preservation capabilities. In the future, paper‐based materials with antimicrobial and hydrophobic functionalities are expected to further enhance food safety as promising packaging materials.

ZnO:V Nanoparticles with Enhanced Antimicrobial Activities

In this study, we used sol-gel to synthesize undoped and V-ZnO nanoparticles with different vanadium concentrations (1, 3, and 5 at.%) under supercritical dry conditions of ethanol. XRD spectra showed that the obtained powders are well crystallized in the hexagonal wurtzite structure of ZnO nanoparticles. The average crystallite size, estimated by the Debye-Scherer formula, was found to be equal to 31 nm for the pure sample, and it was decreased to 27 nm for the 3at.% vanadium-doped one. SEM and TEM photographs indicated the spherical and elongated shapes of the nanoparticles. The stretching bands located at 419 cm−1 confirmed ZnO material formation. The efficacy of the produced ZnO NPs against Gram+, Gram− bacteria, and fungi was tested. Vanadium-doped ZnO, with low concentrations (10 µg/mL), exhibited a large influence on bacterial and fungi growth inhibition. For example, the inhibition zones IZ of S. aureus and E. coli bacteria reached 16 and 15 mm, respectively, for ZnO:V1%, while the IZ of these two bacteria were 14 and 12 mm for the undoped ZnO. The use of V-dopant enhanced the production of the reactive oxygen species ROS by the photogeneration of electron-hole pairs due to light absorption by ZnO in the visible region.

In this study, we used sol-gel to synthesize undoped and V-ZnO nanoparticles with different vanadium concentrations (1, 3 and 5 at.%) under supercritical dry condition of ethanol. XRD spectra showed that the obtained powders are well crystallised in hexagonal wurtzite structure of ZnO nanoparticles. The average crystallites size, estimated by Debye-Scherer formula, was found to be equal to 31 nm for the pure sample and it was decreased to 27 nm for the 3at.% vanadium doped one. SEM and TEM photographs indicated the spherical and elongated shape of the nanoparticles. The stretching bands located at 419 cm-1 confirmed ZnO materials formation. The efficacity of the produced ZnO NPs against G+, G- bacteria and fungi was tested. Vanadium doped ZnO, with low concentrations (10 µg/ml) exhibited a large influence on bacteria and fungi growth inhibition.
