Abstract

Nanotechnology has revolutionized materials research, leveraging nanoscale entities (1–100 nm) with extensive applications across diverse fields. This study explores the synthesis of silver nanoparticles (AgNPs) using aqueous leaf extract of Aegle marmelos (AMLAE) prepared via the decoction method. The Ag+ ions were reduced to Ag0 using AMLAE and without using any chemical for reduction and precipitation. The formation of AM-AgNPs was confirmed through UV-Vis spectroscopy, which exhibited a localized surface plasmon resonance (LSPR) band at 450 nm. Fourier-transform infrared (FTIR) analysis revealed surface functionalization, including O-H, C=C, C=O, and Ag-O bonds. X-ray diffraction (XRD) confirmed a face-centered cubic structure with an average crystallite size of 14.07 nm, while high-resolution transmission electron microscopy (HRTEM) indicated spherical morphology and an average particle size of 16.07 nm. Dynamic light scattering (DLS) analysis showed a hydrodynamic size of 237.5 nm with a polydispersity index (PDI) of 0.243 and a zeta potential of -16.6 mV, indicating colloidal stability. The antimicrobial efficacy of AM-AgNPs was assessed against six pathogens, with minimum inhibitory concentrations (MIC) as low as 15.62 μg mL−1 for Vibrio parahaemolyticus. Photocatalytic degradation of methylene blue (50 ppm) demonstrated a 99.24% degradation efficiency under visible light within 60 minutes. Cytotoxicity studies on Vero cell lines yielded an IC50 value of 253.73 μg mL−1, suggesting low toxicity levels. These findings represent the potential of green-synthesized AgNPs for biomedical and environmental applications, establishing AMLAE as an efficient and sustainable reducing agent.
