Abstract:
Nanotechnology is considered as one of the interesting fields that is fast-growing worldwide and
has an impact on innovation capabilities. Gold nanoparticles (AuNPS) showed various biomedical
applications in recent years. Different physical, chemical techniques have been reported for its
toxicity in the synthesis of Gold nanoparticles (AuNPS) while the green synthesis method is the
safest due to it build on materials less toxic and eco-friendly. Therefore, the current study aimed
to use the parsley (Petroselinum crispum) leaves extract in order to synthesis AuNPs by a simple
eco-friendly method. Different four volume ratios of plant were used named AuNPs(A),
AuNPs(B), AuNPs(C), and AuNPs(D), respectively. The produced NPs were characterized using
UV–vis spectroscopy while the structural and morphological of the formed NPs was performed
via high resolution transmission electron microscope (TEM), Fourier Transform Infrared
Spectroscopy (FTIR), dynamic light scattering (DLS) as well as zeta potential. The TEM images
taken for the formed NPS revealed the formation of particles with average size around 25 nm
possessing semi-spherical shapes. Furthermore, the surface Plasmon resonance appeared at 530
nm. The detection of zeta potential at value less than -30 mV indicts the NPS stability.
