Characterization of silver nanoparticles synthetized by green alternative
Abstract
In this research the green synthesis of silver nanoparticles (AgNPs) was developed using the extract of Thuja orientalis. The nanoparticles were characterized by: UV-Vis spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, particle size by DLS and zeta potential by electrophoretic light. Through UV-Vis spectroscopy a peak at 420 nm was observed, that is attributed to silver nanoparticles (AgNPs) due to their Surface Plasmon Resonance (SPR). The Fourier transform infrared spectra was used to observe characteristic functional groups of phyto molecules involved in the silver-ion binding process such as R—O—H (3,335), O=C-OH (2314 )and C-C=C (1,450). Zeta potential showed the size and electrophoretic light stability of the NPs showed values of 86.82 nm and -19.6 mV respectively. These results showed that Thuja orientalis infusion is an efficient reducer in the synthesis of nanometre-sized particles.
