Abstract
Silver nanoparticles (Ag NPs) were synthesized using Alternanthera sessilis leaf and Oregano root extract in an eco-friendly
fashion and their significant physicochemical and optochemical properties were ascertained for nano-defined characteristics.
The UV–visible spectrum showed a single and distinct absorbance peak at 433 nm (Alternanthera sessilis) and 425 nm
(Oregano), typical SPR (surface plasmon resonance) for silver. Structural studies revealed nano-crystal with face centre
cubic (FCC) symmetry with monodispersed nature. SEM studies showed spherical-shaped particles and the purity determined
from EDX spectrum. The synthesized Ag NPs showed that antibacterial activity was studied. There was a significant
inhibitory effect toward clinicall
