Abstract
Cotyledon orbiculata, commonly known as pig’s ear, is an important medicinal plant of South
Africa. It is used in traditional medicine to treat many ailments, including skin eruptions, abscesses,
inflammation, boils and acne. Many plants have been used to synthesize metallic nanoparticles,
particularly silver nanoparticles (AgNPs). However, the synthesis of AgNPs from C. orbiculata has
never been reported before. The aim of this study was to synthesize AgNPs using C. orbiculata
and evaluate their antimicrobial and immunomodulatory properties. AgNPs were synthesized and
characterized using Ultraviolet-Visible Spectroscopy (UV-Vis), Dynamic Light Scattering (DLS) and
High-Resolution Transmission Electron Microscopy (HR-TEM).
