Micrograph obtained by TEM of AgNPs, as well as size distribution graph and HRTEM. The micrographs show the nanoparticles generated from the extracts of leaves and fruit peels of Annona muricata. The LE-AgNPs generated show an average diameter size of 19.63 ± 3.7 nm (a1) and a quasi-spherical shape (a2). The inter-planar spaces with a distance of 2339 Å were determined for the AgNPs-PE which corresponds to the family of planes (111) (a3). The LE-AgNPs generated show a quasi-spherical shape, individualized AgNPs can be seen without agglomerations (b1). The average diameter size of 16.56 ± 4.1 nm for the AgNPs-PE (b2). The inter-planar distances of the AgNPs-LE were measured, obtaining a distance of 2040 Å, which corresponds to the family of planes (200) (b3).
