Ultrasonic-assisted green synthesis of silver nanoparticles through cinnamon extract: biochemical, structural, and antimicrobial properties

Ultrasonic-assisted green synthesis of silver nanoparticles is gaining more attention owing to its benefits over conventional process. The main objective this study was synthesize with aqueous cinnamon extract using ultrasound-assisted extraction and their physico-chemical characterization. Total phenolic content, DPPH, FRAP were 315 mg GAE/g, 89% scavenging activity 9.5 mmol Trolox eq/100 g reducing power respectively. synthesized characterized by UV-visible spectroscopy, X-rays Diffraction (XRD), Scanning Electron Microscopy (SEM) Energy Dispersive (EDX), Fourier transform infrared (FTIR) Nuclear Magnetic Resonance (NMR). XRD spectra depicted that the crystallite in structure 50 nm size. SEM micrographs showed spherical shape. EDX, FTIR NMR indicated compounds present played role capping ions. Cinnamon-based potential antimicrobial against Gram negative Gram-positive bacteria. Thus, obtained through ultrasonic-assisted could be a valuable source polyphenols, which actively participated reduction stabilization nanoparticles.
