“…However, Ag NPs exhibit the most active antibacterial activity according to different forms of silver. [8,36] The crosslinked RawF-CL film exhibited 100% antibacterial activity for E. coli. This result was associated with the presence of GLA in the RawF-CL film.…”

“…Ag that enters the body does not accumulate and 90%-99% is excreted from the body in 2-4 days through feces and urine. [8] Polyvinyl alcohol (PVA), a biocompatibility and biodegradable synthetic polymer is very suitable for use as a food packaging material, owing to its odorless and transparent, nontoxic, excellent film-forming ability. Due to the presence of many hydroxyl groups in the PVA structure, it shows a high hydrophilic feature and is soluble in water due to this feature.…”

In this study, composite films were produced with the solution casting method from prepared solutions by adding 1%, 3%, 5%, and 7% silver nanoparticles (Ag NPs) to blends 60/40 (w/w) ratio of polyvinyl alcohol and sodium caseinate (NCS). Afterward, the films were crosslinked by dipped in a glutaraldehyde bath. This crosslinking method applied to the films did not cause any adverse effects on the surface views of the films. The occurred aldehyde groups confirmed crosslinking. The thermal stability increased with crosslinking and increasing Ag NPs amount. The 1% Ag NP added film showed the highest tensile strength compared with the crosslinked raw film. The lowest moisture content was observed in 5% and 7% AgNP‐added films. The used crosslinking method increased the crosslinking efficiency compared with the crosslinking method in solution, ensuring a decrease in the total soluble matter (TSM) amount of the films. In addition, the TSM value continued to decrease proportionally with the increasing amount of Ag NP compared with the raw crosslinked film. Through the lowest swelling rate, the 3% AgNP‐added film exhibited the highest crosslinking density. While the water vapor permeability rate of the crosslinked raw film increased, a proportional decrease was observed by increasing Ag NPs. The 7% Ag NP added film exhibited the best barrier property. All films showed antibacterial activity against Escherichia coli and Staphylococcus aureus. It is suggested that the produced composite films can be used as food packaging with an antibacterial effect. Highlights PVA/NCS/Ag NPs blended composite films were obtained. The composite films were crosslinked in the glutaraldehyde bath. The crosslinked films exhibited high antibacterial activity. Low water vapor permeability and low swelling behavior were observed on films. Crosslinked PVA/NCS/Ag NPs films were suggested to be used as food packaging.

“…The antimicrobial activity of CH‐graft‐poly( N ‑ tert ‑BAAm)/neodymium composites was investigated against Gram‐negative ( E. coli and P. aeruginosa ) and Gram‐positive ( B. subtilis and S. aureus ) bacteria. These bacteria used in our study were preferred because they are widely used in other polymers [28]. The diameter of the zone of inhibition was used, which represents the inhibitory effect on the growth of bacteria.…”

In this present study, composites of chitosan‐graft‐poly(N‐tertiary butylacrylamide) (CH‐graft‐poly(N‑tert‑BAAm)) copolymer, with Neodymium (Nd), an important rare earth element, were prepared by precipitation technique. Nd was successfully incorporated into the polymer of different weight percentages (0.5%, 1%, and 2%) without any degradation. The effect of neodymium additives on the structural, morphological, and antibacterial activities against gram‐positive bacteria and gram‐negative bacteria of the polymer was analyzed using various instrument techniques. X‐ray diffraction (XRD) results together with Fourier Transform Infrared (FT‐IR), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) studies confirmed the morphology of Nd‐doped CH‐graft‐poly(N‑tert‑BAAm) composites without any other impurities. The antibacterial effect of Nd was studied by adding it to the copolymer in a weight ratio of 0.5%–2%. The antibacterial effect of neodymium concentration on four different strains of bacteria was investigated: Escherichia coli (ATCC 25922) (E. coli), Pseudomonas aeruginosa (DSM 50071) (P. aeruginosa), Bacillus subtilis (DSM 1971) (B. subtilis), and Staphylococcus aureus subsp. aureus (ATCC 25923) (S. aureus). The antibacterial activities of the obtained composites were determined using the Agar Well Diffusion Assay Method. Experimental results show that Nd binds well to CH‐graft‐poly(N‑tert‑BAAm). Activity against E. coli, P. aeruginosa, B. subtilis, and S. aureus subsp. aureus creates a potential for pharmaceutical and biomedical applications.

“…[80,81] In addition to SF, the shift in the decomposition temperatures, in this case, can be attributed to the thermal resistance of homogeneously dispersed Ag NPs in the fibers due to their slow-release time, which has been demonstrated in other studies also.

The hydrophobicity of polyurethane fibers is undesired for tissue engineering. In this work, fibers are fabricated by electrospinning and coated with silk fibroin (SF) for biocompatibility and biologically synthesized silver (Ag) nanoparticles (NPs) for antibacterial activity. The scanning electron microscopy revealed the undistorted morphology and the presence of NPs on fibers. The Fourier transform infrared and thermogravimetric analysis show the successful incorporation of SF and Ag NPs. The water contact angle drops from 101.26±0.2° in pristine to 3.1±0.3° in the hydrothermally treated fibers. The moisture regain from 1.87±0.3% to 6.7±0.4% is observed after 24 h. The mineralization shows the hydroxyapatite NPs in all composites. The large zone of inhibition is observed in the composite, with the Ag NPs equal to 11.5±0.04 mm for Staphylococcus aureus and 18.91±0.02 mm for Escherichia coli. The increased proliferation of HEK 293T cells for 6 days of culture on composite scaffolds compared to the pristine scaffolds is achieved. The cell attachment examinations show successful attachment of cells on fibers and nuclear staining analysis shows the highest proliferation in scaffolds with an intermediate concentration of Ag NPs (10%). This strategy presents a novel improvisation for as‐spun PU fibers that can fabricate wound‐healing biomaterials for tissue engineering.
