“…8,9 Therefore, extensive recent research has focused on the exploration of new and efficient antibacterial substances, such as nanoparticles composed of metals (MNPs) and metal oxides (MONPs). [10][11][12] The therapeutic efficacy of MONPs in many biomedical applications has received worldwide attention, 13 due to their special physical and chemical characteristics, such as high bioavailability, excessive reactive oxygen species (ROS), and vital oxidative stress (OS). 14,15 Green-based synthesis of MNPs and MONPs has gained significant attention because it overcomes many environmental concerns raised by traditional chemical-based synthesis methods.…”

“…A sharp decrease in cell viability was found with an additional increase in AgNP concentration from 9 to 12 μg/mL, indicating that the cytotoxicity of the AgNP‐decorated vesicles was significantly higher for the A549 cells at this concentration. The toxicity of the AgNPs was high and could destroy the structure of the bacterial cell membranes [22,44] . However, the produced AgNP‐decorated vesicles were safe for the A549 cells within the concentrations of the MIC values for the AgNPs.…”

Silver/polymeric vesicle composite nanoparticles with good antibacterial properties were fabricated in this study. Silver nanoparticles (AgNPs) were prepared in situ on cross‐linked vesicle membranes through the reduction of silver nitrate (AgNO3) using polyvinylpyrrolidone (PVP) via coordination bonding between the Ag+ ions and the nitrogen atoms on the vesicles. X‐ray diffraction (XRD), ultraviolet‐visible spectroscopy (UV‐vis), and transmission electron microscopy (TEM) analyses confirmed the formation of AgNPs on the vesicles. The antibacterial test demonstrated good antibacterial activity against both Gram‐negative bacteria (Escherichia coli) and Gram‐positive bacteria (Staphylococcus aureus) for the produced AgNP‐decorated vesicles. The minimum inhibitory concentration (MIC) values of the AgNP‐decorated vesicles for E. coli and S. aureus were 8.4 and 9.6 μg/mL, respectively. Cell viability analysis on the A549 cells indicated that the toxicity was low when the AgNP concentrations did not exceed the MIC values, and the wound healing test confirmed the good antibacterial properties of the AgNP‐decorated vesicles.

“…Samples of composite film were cut to a suitable size and were pasted flat onto the sample platform. An X‐ray diffractometer (XRD, Bruker, Karlsruhe, Germany) was then used to analyze the crystallization properties of the film, under the following conditions: voltage, 40 kV; current, 40 mA; scan speed, 8°/min; and scan range, 5° to 60° [27] …”

A sodium alginate/silk sericin (SA/SS) film was modified with glycerin (GI) and Polygonatum sibiricum polysaccharide@silver nanoparticles (PSP@AgNPs) to create a SA/SS/GI/PSP@AgNP composite film with antibacterial and antioxidant properties. The physicochemical properties of the SA/SS/GI/PSP@AgNP composite film were analyzed, and its cytocompatibility, antioxidant activity, and antibacterial properties were investigated. The optimum conditions for the preparation of the SA/SS/GI/PSP@AgNP composite film were 2 % SA, 2 % SS, 20 % GI, and 40 μg/mL of PSP@AgNPs. The addition of GI improved the surface smoothness of the composite films, while the presence of PSP@AgNPs did not significantly alter it. Spectroscopic characterization demonstrated that GI and PSP@AgNPs were physically bound to SA/SS. Approximately 53 % of the PSP@AgNP was released from the SA/SS/GI/PSP@AgNP composite film over 24 h of soaking in aqueous solution. The resulting leaching solution did not cause hemolysis or cytotoxicity, indicating its biocompatibility. Additionally, the SA/SS/GI/PSP@AgNP composite film exhibited strong antioxidant and antibacterial properties, and it promoted healing of mouse wounds infected with Staphylococcus aureus.
