ABSTRACT |
|
|
|
This paper describes a simple
biosynthesis of silver nanoparticles (SNPs) from aqueous leaves
extract of Acacia arabica
(AA), a natural product. The formation of SNPs was confirmed and
optimized by measuring surface plasmon resonance (SPR) peak around
420 nm using UV-visible spectroscopy (UV-Vis). The possible
functional groups of AA leaves extract and their changes after
treating with aqueous silver nitrate were evaluated by Fourier
transform infrared spectroscopy (FTIR). The size of synthesized SNPs
was measured by Zetasizer analyzer analysis and morphology was
examined by scanning electron microscopy (SEM) in the nano range.
The average size of SNPs is ~30 nm and monodispersed. Antibacterial
activity of AA-SNPs was studied taking into account Bacillus
subtilis (bacillus) and Escherichia coli. The characteristics of the
facial AA-SNPs formed suggest biomedical application as chemical
sensors in the future.
