Summary: In this study, the stability and antibacterial activity of silver nanoparticles (AgNPs) coated with different stabilizers were investigated. The AgNPs showed differences in stability and size change depending on the coating agent used. The stabilizer may function as a growth controller of the nanoparticles, affecting their biological properties. The protective or stabilizing agents also played a role in the antibacterial capacity and stability of AgNPs over time.

Summary: The study aimed to enhance the bioactivity of electrospun PCL membranes by coating them with bioactive lactose-modified chitosan (CTL), which can be used for the synthesis and stabilization of silver nanoparticles to provide antibacterial properties. The CTL coating improved MG63 osteoblast adhesion and proliferation, while discouraging biofilm formation by Pseudomonas aeruginosa and Staphylococcus aureus.

Summary: This study aimed to fabricate Zataria multiflora-derived silver nanoparticles (AgNPs) and compare their antibacterial and biofilm inhibitory activities against Staphylococcus aureus ATCC 25923 with commercial AgNPs. The plant-mediated fabricated AgNPs (P-AgNPs) exhibited significant antibacterial activity and biofilm inhibition at lower concentrations, showing stronger effects compared to commercial AgNPs.

Summary: A new hybrid antibacterial agent (SLP-AgNPs) was prepared by using silver nanoparticles and Lactobacillus buchneri-isolated surface-layer proteins, showing significantly enhanced antibacterial activity. The synergistic antibacterial mechanism of SLP-AgNPs may be achieved through the enhanced adhesion to bacteria, antibacterial ability of SLP, and sustained release of silver ions.

Summary: In this study, azoimidazole compounds with potent antifungal activity were conjugated with silver nanoparticles, resulting in synergistic antimicrobial activity. The conjugates exhibited improved antimicrobial activity against microorganisms, particularly bacteria, with concentrations below their individual MIC. Additionally, some combinations were found to be non-cytotoxic towards human cells.

Summary: This study focused on the synthesis of silver nanoparticles and their antibacterial activity. The use of nitric acid to adjust the pH during synthesis produced larger and more varied particle sizes. The silver nanoparticles were successfully loaded onto clay minerals and exhibited strong antibacterial effects. Additionally, the cytotoxicity of the silver-loaded samples was found to be low.

Summary: This study successfully obtained stable star polymer layers with incorporated silver nanoparticles (AgNPs) and evaluated their antimicrobial activity. The synthesis of AgNPs directly by the star polymer layer was achieved by covalently binding polymeric stars with solid supports. The formation of AgNPs using only amine groups of the star arms and their efficacy were confirmed through analysis of layer thickness, water affinity, and silver incorporation. The prepared nanolayers demonstrated high antibacterial effectiveness against both gram-positive and gram-negative bacteria strains.
