Synthèse verte des nanoparticules d’argent a l’aide de l’éxtrait de l’écorce de cannelle

Abstract

anotechnology, a multidisciplinary field, merges knowledge from various scientific domains. Among the most widespread nanomaterials are silver nanoparticles (AgNPs), which are widely used. The green synthesis of silver nanoparticles from plant extracts offers an alternative to traditional synthesis methods. This study focuses on the biosynthesis of silver nanoparticles from cinnamon bark extract (Cinnamomum zeylanicum Blume). The typical peaks obtained by UV-vis at 425 nm confirm the synthesis of AgNPs, and this analysis revealed the influence of different parameters, notably time, light, concentration of NO3 solution, and the volume of cinnamon extract. The results obtained by infrared spectra show that the compounds in the Cinnamomum zeylanicum Blume bark extract may be responsible for the synthesis of AgNPs.
