Gold nanoparticles (AuNPs) were synthesized using mulberry leaf extract and HAuCl4.
solution at room temperature and household microwave by applying two different methods in this
study. Freshly leaves of Mulberry were collected from the Eastern Black Sea region (TRABZON)
in Turkey. Firstly, 10 g of dried sample was shaken in 100 mL of distilled water- citric acid
(0.1 M) mixture (1:1) for 90 min at room temperature and extracted in a laboratoary microwave
device at 4 minutes, 600 W and left cooling. For the biosynthesis of Au-NPs, the different
volume of leaf extract (0.5 and 1 mL) was added HAuCl4. 3H2O solution (0,5 mM-1 mM) at
room temperature (First method). In second method, the same mixture was exposed to a
household microwave at 90 W for 1–60 min. Gold nanoparticles were characterized using UVvisible absorption spectroscopy and FT-IR. UV-Vis absorption spectrum of Au-NPs was done in
UV-Vis spectrophotometer (Shimadzu UV-1240) in a wave length range from 300 to 800 nm 1
.
The characteristic plasmon resonance peak of gold nanoparticles was observed at around 538-550
nm. The color of the mixture was purple-red indicating the formation of Au-NPs 2
. All
experimental work was repeated three times
