Abstract:
This study reports the biosynthesis of Chromoleana odorata mediated silver nanoparticles (AgNps) under ambient temperature. The biosynthesized nanoparticle was characterized by UV-visible spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and scanning electron microscopy. The AgNp solution produced a shade of colours from yellow through brown to dark brown within a period of 10 minutes with a maximum absorbance at 444.50 nm. The FTIR showed strong peaks at 3423.76 cm-1 and 1629.90 cm-1, indicating that proteins acted as the capping and stabilization molecules in the biotransformation process of silver AgNps. The scanning electron microscope revealed that the Chromoleana odorata mediated AgNps are slightly spherical.
