    Biosynthesis of silver nanoparticles using bitter leave (Veronica amygdalina) for antibacterial activities
    (ScienceDirect, 2019) Botha, Subelia S
    A green and facile biosynthesis of silver nanoparticles (SNPs) using dry Bitter leaves (DBL) (Vernonia amygdalina) aqueous extract as a capping and reducing agent was demonstrated in this work. The effect of the precursor's concentration on the size and shape of SNPs and its antibacterial activity is evaluated. The synthesized DBL_SNPs were characterized by using UV–visible spectroscopy, Fourier transforms infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
