“…Focusing our interest on silver nanoparticles (Ag-NPs), these have been widely used in medicine and biotechnology fields, due to their properties as antimicrobials. In this sense, numerous research studies have confirmed the effectiveness of Ag-NPs to inhibit the growth of pathogenic bacteria such as Staphylococcus aureus, Streptococcus mutans, Streptococcus pyogenes, Escherichia coli and Proteus vulgaris [10][11][12]. Interestingly, this activity has been also demonstrated using Ag-NPs obtained by 'biological methods' which are considered a great tool to reduce the negative effects associated with traditional nanoparticle synthesis commonly used in the laboratory [13].…”

Foodborne diseases are one of the factors that endanger the health of consumers, especially in people at risk of exclusion and in developing countries. The continuing search for effective antimicrobials to be used in the food industry has resulted in the emergence of nanotechnology in this area. Silver nanoparticles (Ag-NPs) are the nanomaterial with the best antimicrobial activity and therefore, with great potential of application in food processing and packing. However, possible health effects must be properly addressed to ensure food safety. This review presents a detailed description on the main applications of Ag-NPs as antimicrobial agents for food control, as well as the current legislation concerning these materials. Current knowledge about the impact of the dietary exposure to Ag-NPs in human health with special emphasis on the changes that nanoparticles undergo after passing through the gastrointestinal tract and how they alter the oral and gut microbiota, is also summarized. It is concluded that given their potential and wide properties against foodborne pathogens, research in Ag-NPs is of great interest but is not exempt from difficulties that must be resolved in order to certify the safety of their use.

“…Finally, the excess of pyrrole completely reduces the silver ions to zero-valent silver, forming silver nanoparticles. Moreover, their nucleation and growth in the core ZnO are protected by the formed PPy shell by interfacial polymerization of pyrrole via H 2 O/CHCl 3 interface, which eventually results in forming the ZnO–Ag/PPy nanocomposite [ 17 , 29 ]. In addition, microwave radiation initiated the oxidation for forming PPy.…”

“…Different shapes of PPy/Ag nanoparticles NPs have been fabricated as core/shell structure, nanorod, and nanofibers in previous papers [ 27 , 28 ]. Ag NPs have attracted great interest in the literature due to their nontoxicity, excellent biocompatibility, high adsorption capacity due to large surface area to volume ratio, high antimicrobial properties, and reusability [ 19 , 29 ]. On the other hand, PPy as a conductive polymer with metal oxide nanocomposites has brought out more fields of water treatment application.…”

Incorporating nanostructured metal and metal oxide in a polymer matrix is a strategic way to develop a novel candidate for water bioremediation. In this study, under microwave irradiation, a ZnO–Ag/polypyrrole (PPy) nanocomposite with a core/shell structure was prepared by interfacial polymerization of pyrrole in the presence of ZnO nanoparticles and AgNO3 as an oxidant. The antimicrobial behavior of the ZnO–Ag core combined with the electrical properties of the conducting PPy shell created a special ZnO–Ag/PPy nanocomposite with inherent adsorption behavior and antimicrobial properties. More impressively, the as-prepared ZnO–Ag/PPy displayed enhanced adsorption of Cd2+ and PO43− ions in the mixed solution. At pH 8, it had overall removal efficiencies of 95% and 75% for Cd2+and PO43− ions, respectively. The Freundlich adsorption model, rather than the Langmuir adsorption model, better fits the adsorption isotherm results. The adsorption kinetics also followed the pseudo-second-order kinetic model. Additionally, the engineered nanocomposite demonstrated antifungal activity against different fungi, as well as remarkable antibacterial activity against Gram-negative and Gram-positive bacteria. The synergistic combination of crystallinity, coherence of the ZnO–Ag core in the PPy matrix, and the negative zeta potential all contribute to this nanocomposite’s high efficiency. Our results have significant consequences in the wastewater bioremediation field using a simple operation process.

“…Silver nanoparticles (AgNPs) are more efficient against pathogenic microbes such as viruses, bacteria, yeast, and fungus [ 13 , 14 , 15 ]. The antagonistic action of silver nanoparticles (AgNPs) against microorganisms can be attributed to two forms, which are the Ag 0 and Ag + species.…”

Nanoparticles (NPs) have acquired significance in technological breakthroughs due to their unique properties, such as size, shape, chemical composition, physiochemical stability, crystal structure, and larger surface area. There is a huge demand for packaging materials that can keep food fresher for extended periods of time. The incorporation of nanoscale fillers in the polymer matrix would assists in the alleviation of packaging material challenges while also improving functional qualities. Increased barrier properties, thermal properties like melting point and glass transition temperatures, and changed functionalities like surface wettability and hydrophobicity are all features of these polymers containing nanocomposites. Inorganic nanoparticles also have the potential to reduce the growth of bacteria within the packaging. By incorporating nano-sized components into biopolymer-based packaging materials, waste material generated during the packaging process may be reduced. The different inorganic nanoparticles such as titanium oxide, zinc oxide, copper oxide, silver, and gold are the most preferred inorganic nanoparticles used in food packaging. Food systems can benefit from using these packaging materials and improve physicochemical and functional properties. The compatibility of inorganic nanoparticles and their various forms with different polymers make them excellent components for package fortification. This review article describes the various aspects of developing and applying inorganic nanoparticles in food packaging. This study provides diverse uses of metals and metal oxides nanoparticles in food packaging films for the development of improved packaging films that can extend the shelf life of food products. These packaging solutions containing nanoparticles would effectively preserve, protect, and maintain the quality of the food material.
