“…Based on the data from the literature, it can be stated that, along with the increase in inhibition zone of the antimicrobial component, its diffusion capacity also rises [51,52]. The obtained results indicate that selected films with the addition of nanoparticles can have an antimicrobial effect, without the diffusion of active ingredients into the environment.…”

Nanocomposite films that were based on furcellaran (FUR) and nanofillers (carbon quantum dots (CQDs), maghemite nanoparticles (MAN), and graphene oxide (GO)) were obtained by the casting method. The microstructure, as well as the structural, physical, mechanical, antimicrobial, and antioxidant properties of the films was investigated. The incorporation of MAN and GO remarkably increased the tensile strength of furcellaran films. However, the water content, solubility, and elongation at break were significantly reduced by the addition of the nanofillers. Moreover, furcellaran films containing the nanofillers exhibited potent free radical scavenging ability. FUR films with CQDs showed an inhibitory effect on the growth of Staphylococcus aureus and Escherichia coli. The nanocomposite films were used to cover transparent glass containers to study the potential UV-blocking properties in an oil oxidation test and compare with tinted glass. The samples were irradiated for 30 min. with UV-B and then analyzed for oxidation markers (peroxide value, free fatty acids, malondialdehyde content, and degradation of carotenoids). The test showed that covering the transparent glass with MAN films was as effective in inhibiting the oxidation as the use of tinted glass, while the GO and CQDs films did not inhibit oxidation. It can be concluded that the active nanocomposite films can be used as a desirable material for food packaging.

“…The neat CS shows the characteristic peaks of typical fingerprints of semi crystallinity CS at 2θ values of about 11°and 20°. [33] For the XRD pattern of CS-MCR/Cu 2 O bio-nanocomposite, the diffraction peaks at 2θ = 29.7°, 36.6°, 42.4°, 61.5°a re respectively well corresponding to (110), (111), (200), (220) planes of cubic-structured Cu 2 O. [34] Besides, the wide peak at 2θ value of 11°and 20°are related to the typical nature of CS.…”

A novel bio‐nanocomposite nanocatalyst with highly dispersed particles is synthesized through covalent functionalization of chitosan biopolymer by the multicomponent reaction (MCR) strategy. Surface functionalization of chitosan through MCR is led to the grafting of carboxamide type ligands with a high affinity toward complexation with copper nanoparticles. The catalytic activity of the synthesized catalyst was explored in various transformations such as A3 coupling and click reactions in water. Reusability and non‐hazardous nature of the catalyst, mild reaction conditions, operational simplicity, high yielding, and using water as a solvent are the main advantages of this catalytic protocol.

“…The combination of CuNPs with chitosan could improve the adhesivity, bioactivity and biocompatibility of the metallic nanoparticles. Several works have reported the preparation of antimicrobial bulk nanocomposites produced by the incorporation of copper and silver nanoparticles into chitosan matrices [8][9][10] . In the current study, the preparation of hybrid copper-chitosan particles with nanometric dimensions is presented.…”
