“…There are many methods to introduce AgNPs onto cotton bers (Bacciarelli-Ulacha et al 2014;Nam and Condon 2014;Pan et al 2018;Ravindra et al 2010), including directly deposition (Cheng et al 2013), padding (Lee et al 2003), layer-by-layer disposition (Xu et al 2016;Xu et al 2017), in situ synthesis (Lee et al 2007;Montes-Hernandez et al 2021), heat evaporation (Smetana et al 2005), etc. The antibacterial mechanism of AgNPs is considered to be the silver ions (Ag + ) gradually release from the surface of AgNPs, which can penetrate into the cell wall and kill the surrounding bacteria (Maneerung et al 2008).…”

Silver nanoparticles (AgNPs) loaded on the cotton ber can endow the ber with good antibacterial activity, but the AgNPs on the surface of cotton ber will leach out with the increase of washing times, which will not only greatly reduce the antibacterial properties of cotton ber, but also cause pollution to the environment. In this paper, carboxyl groups were introduced into cotton ber by three methods, namely selective oxidation, butane tetracarboxylic acid (BTCA) grafting and polyacrylic acid (PAA) adsorption. The silver ions (Ag + ) were adsorbed on the cotton bers through electrostatic attraction, and after reduction, the AgNPs were loaded onto the cotton bers, and the AgNPs distribution on the ber and its effect to the washing resistance of AgNPs were studied. The results showed that the selective oxidation and the BTCA grafting can introduce carboxylic groups into the interior of cotton bers while the PAA adsorption only imports carboxyl groups on the surface of the ber. As a consequence, AgNPs were formed inside of the cotton ber when the selective oxidation and the BTCA grafting were employed, while AgNPs can only be loaded on the surface of the ber by the PAA adsorption method. AgNPs inside of the ber have high energetic adherence, resulting in silver-cotton fabric nanocomposites with strong slow-release property and long-term antibacterial ability. The fabric nanocomposites prepared by selective oxidation and BTCA grafting exhibited high AgNPs retention rate and excellent antibacterial activity even after 80 washing cycles.

“…In recent decades, silver nanoparticles (Ag NPs) have been intensively investigated for their unique physical, chemical, and biological properties which underpin applications in various fields, including antibacterial devices 1 – 3 , electric coatings 4 , 5 , sensors 6 , 7 , and catalysts 8 , 9 . It is especially noteworthy that Ag NPs are an important type of broad-spectrum antibacterial materials that show excellent activity against almost all microorganisms; this activity appears to derive from the large surface area which can generate Ag + much faster than bulk silver metal, allowing wide application in medical science 10 – 12 .…”

Silver nanoparticles (Ag NPs) system capable of exhibiting different particle size at different temperature was developed, which depended on the extent of Diels–Alder (DA) reaction of bismaleimide with furan. Thus, Ag NPs were functionalized on the surface by a furyl-substituted carbene through an insertion reaction. Subsequent reversible DA crosslinking achieved a controlled aggregation with different particle size, which gives a series of different antibacterial activity. These Ag NPs were characterized by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectroscopy (XPS), and Nanoparticle Size Analyzer. The aggregation of the Ag NPs could be reliably adjusted by varying the temperature of DA/reverse-DA reaction. The antibacterial activity was assessed using the inhibition zone method against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), which decreased first and then increased in agreement with the size evolution of Ag NPs. This approach opens a new horizon for the carbene chemistry to modify silver nanoparticles with variable size and give controlled antibacterial activity.

“…coli, respectively. Rosin presented a unique fused-ring structure, and the antibacterial activity may be stronger because of the interaction between the polymer and the bacteria. ,, Comparative test of the grape package with our samples were compared; their appearance at the beginning, 1st day, 3rd day, 7th day, and 11th day is provided in Figure g. The grape coated with neat PHBV began to decay according to the surface in the seventh day.…”

Rosin and cellulose nanocrystals (CNCs) are easily extracted from agricultural pines/conifers and natural cellulose, and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is extracted from agricultural corn stalks, etc. In this study, PHBV and CNC-grafted rosin (CNC-R) hybrids were successfully fabricated by an efficient solution casting. The nanocomposites with a homogenous microstructure were transparent and had strong barrier resistances to water vapor and two food simulants. The synchronous enchantments in mechanical strength/toughness and thermal stability of nanocomposite films were achieved by addition of CNC-R. The T 0 increased by 31.2 °C for the film with 10 wt % CNC-R; meanwhile, the tensile strength and elongation to break were improved by 107.9 and 43.9% for the sample using 5 wt % CNC-R, respectively. Also, compared to neat PHBV, the nanocomposites with 5 wt % CNC-R exhibited excellent barrier properties, antibacterial activity (100.0% antibacterial ratio), and lower migration levels for both food simulants. The appearance of coated grapes with 10 wt % CNC-R nanocomposites at the 11th day was the best compared to those of PHBV and its nanocomposites with a low CNC-R content (1−3 wt %). Thus, our nanocomposites with CNC-R showed a significant application in packaged grape by extended shelf life and had potential applications in bioactive food packaging materials.
