*2.6. Characterization of the Biosynthesized AgNPs*

Characterization of the biosynthesized AgNPs was performed by using several techniques. Fourier transform infrared (FTIR) was performed to identify the functional groups of the CFSs responsible for reducing Ag ion to AgNPs; transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive spectrum (EDS) as well as X-ray diffraction (XRD) were performed to study the size and morphology and to ensure the presence of silver ion in the resulting pellets of AgNPs.
