“…It was proved that AgNPs and AgNWs showed effective antibacterial activity on both Gram negative and Gram positive bacteria. 14,38,[50][51][52][53][54] Moreover, in the presence of AgNPs, the bacterial activity of E. coli is usually higher than that of Staphylococcus aureus. 52 Therefore, E. coli was selected to determine the antibacterial activity based on the diameter of the growth inhibition zone in this wok.…”

Wearable electronic textiles with high conductivity and excellent antibacterial activity are very desirable to minimize health risks and deteriorated performance of the electronic textiles in application. In this work, conductive fabrics were prepared with chitosan nonwovens with inherent antibacterial activity as the substrate. Silver nanoparticles (AgNPs) were synthesized in situ on the surface of chitosan fabric without any additional reducing agent, and silver nanowires (AgNWs) were adhered to the surface of AgNPs-coated chitosan fabrics by simple dip-coating cycles. The synergy of AgNPs and AgNWs enhances the conductivity of the fabric and the stability of AgNPs on the surface of the fabric. According to the analysis of scanning electron microscope and fourier transform infrared spectroscopy spectra, AgNPs were reduced in situ on the fabric. With synergy of AgNPs and AgNWs, the electrical resistance of the fabric is as low as low as 0.93 Ω/sq and 0.20 Ω/sq after one and four dip-coating cycles of AgNWs respectively. Thermogravimetric analysis and inhibition zone assay showed that combination of AgNPs and AgNWs enhanced the thermal stability and antibacterial activity of chitosan fabrics. The chitosan fabrics with conductivity, thermal stability and antibacterial activity can be used in electronic textiles for different applications.

“…Coating is introduced onto the surface of an engraved roll, then it is partially submersed in or by an enclosed applicator head that holds the coating against the roll [131]. [132][133][134] Each method can be considered a valid technique for wet coating application and the specific choice depends on the physico-chemical features of the coating and the surface properties of the chosen substrate. For instance, coatings based on polysaccharides or proteins exhibit a considerably polar component in terms of surface energy, while the cutin, composed of ω-hydroxy acids, forms hydrophobic films [135].…”

The development of new bio-based coating materials to be applied on cellulosic and plastic based substrates, with improved performances compared to currently available products and at the same time with improved sustainable end of life options, is a challenge of our times. Enabling cellulose or bioplastics with proper functional coatings, based on biopolymer and functional materials deriving from agro-food waste streams, will improve their performance, allowing them to effectively replace fossil products in the personal care, tableware and food packaging sectors. To achieve these challenging objectives some molecules can be used in wet or solid coating formulations, e.g., cutin as a hydrophobic water- and grease-repellent coating, polysaccharides such as chitosan-chitin as an antimicrobial coating, and proteins as a gas barrier. This review collects the available knowledge on functional coatings with a focus on the raw materials used and methods of dispersion/application. It considers, in addition, the correlation with the desired final properties of the applied coatings, thus discussing their potential.

“…The lactic acid-coated film has been reported to reduce the 49% oxygen transmission rate and 47% water transmission rate. 24 Silver nanoparticles polyvinylpyrrolidone (PVP)-based glycerosomes has been used as a coating, and it was reported to increase the shelf life of fresh-cut bell pepper for 12 days at 4 C. 25 In a study, the incorporation of Accasellowiana extract and silver nanoparticles in polyethylene oxide films has been reported to show the antimicrobial and antioxidant properties other than the preferred mechanical properties. Also, the film is biodegradable, which can be used as an innovative food packaging material.…”

Silver nanoparticles are broad‐spectrum antimicrobials which, in recent years, have gained much attention in food packaging. Nowadays, minimally processed foods are demanded by consumers with better quality and wholesomeness. Foods reach the consumer's table because of the packaging, which plays an essential function in protection, convenience, information and promotion. Safety due to conventional packaging can be improved with the help of antimicrobial agents by incorporation or coating. Silver being an excellent antimicrobial agent has been used in food packaging to improve packed foods shelf life. There is a need to summarize the studies on the migration of silver nanoparticles from packaging to food and their toxicity. In this review, we have outlined the function of silver nanoparticles in food packaging, their toxicity and their effect on the environment.
