How does the presence of L-Arginine affect the synthesis and properties of Ag/AgCl nanoparticles when using sugar ligands?

Label:chem

Topic
Silver chloride (AgCl) nanoparticles (AgCl_NPs) have various applications in biological, biomedical, and industrial fields. The morphology, size, and surface chemistry of these nanoparticles are crucial for their performance. This study investigates how the presence of L-Arginine hydrochloride and different sugar ligands (Lactose p-methoxyaniline (LMA), Galactose 5-aminosalicylic acid (G5AS), Lactose sulfanilic acid (LSA), and Lactose psulfonyldianiline (LPSA)) influence the formation and properties of Ag/AgCl nanoparticles.
Answer
The presence of L-Arginine significantly affects the synthesis and properties of Ag/AgCl nanoparticles. L-Arginine interacts with silver ions and influences the interaction between sugar ligands and silver ions, altering the morphology, size, and surface chemistry of the nanoparticles. For example, LMA and G5AS ligands result in sheet-like Ag/AgCl nanoparticles, while LSA and LPSA ligands cause the formation of anisotropic and film-like nanoparticles. The introduction of L-Arginine enhances the antibacterial activity of the nanoparticles against multidrug-resistant Escherichia coli species, independent of the sugar ligand chemistry and nanoparticle morphology and size.
