To establish a simple, one-step synthesis for size-controlled silver colloid nanoparticles using reducing sugars and assess their antibacterial efficacy against diverse bacterial strains.
Synthesized silver colloids by reducing diamminesilver(I) complexes with glucose, galactose, maltose, or lactose across varying ammonia concentrations (0.005–0.20 mol/L) and pH levels (11.5–13.0).
Characterized particle size distributions and morphology using dynamic light scattering (DLS), transmission electron microscopy (TEM), and UV/Vis spectrophotometry, followed by in vitro antibacterial assays against Gram-positive and Gram-negative pathogens.
Syntheses generated silver nanoparticles spanning 25 to 450 nm, with maltose reduction yielding the smallest average diameter of 25 nm and narrow size distributions at lower ammonia concentrations.
Nanoparticles demonstrated size-dependent bactericidal efficacy against Gram-positive and Gram-negative bacteria, including methicillin-resistant Staphylococcus aureus, at concentrations as low as 1.69 µg/mL Ag.
