Green Synthesis of Silver Nanoparticles Using Apple Extract and Its Antibacterial Properties

Abstract EN

Silver nanoparticles (AgNPs) were synthesized using apple extract as a reducing agent and aqueous silver nitrate as the precursor.

The AgNPs formation was observed as a color change of the mixture from colorless to dark-brownish.

The X-ray diffraction pattern confirmed the presence of only Ag crystallites, and the dynamic light scattering estimates the average sizes of the AgNPs to be 30.25 ± 5.26 nm.

Furthermore, Fourier Transform Infrared as well as UV-vis spectroscopy identifies ethylene groups as the reducing agent and capping agent for the formation of the AgNPs.

This green synthesis provides an economic, eco-friendly, and clean synthesis route to AgNPs.

AgNPs in suspension showed activity against Gram-negative and Gram-positive bacteria with minimum bactericidal concentrations (MBCs) to be in the range from 125 μg/mL to 1000 μg/mL.
