Abstract
Biological methods of nanoparticle synthesis using plant extracts have been suggested as promising ecofriendly alternative to chemical and physical methods. In this study, spherical silver nanoparticles (AgNP) were synthesized from the aqueous extract of Mimusops coriacea leaves at room temperature. To accelerate the reduction of Ag+ ions was used photoreduction process with Xenon lamp. A presence of resonant surface plasmon band at approximately 415 nm confirms the formation of the nanoparticles. The shape and size of the particles were determined by transmission electron microscopy images indicating sizes from 10 to 30 nm in diameter. Zeta potential indicates good stability. To identify the products for the reduction of Ag+ ions and stability of AgNP, FTIR analysis were performed. An intense reduction in chlorophyll fluorescence was observed after formation of the nanoparticles.
