      This study reports a green method for the synthesis of gold   nanoparticles using the aqueous extract of rose petals. The   effects of gold salt concentration, extract concentration and   extract quantity were investigated on nanoparticles synthesis.   Gold nanoparticles were characterized with different techniques   such as UV–vis spectroscopy, FT-IR spectroscopy, X-ray   diffraction, energy dispersive X-ray spectroscopy, dynamic light   scattering and transmission electron microscopy. Transmission   electron microscopy experiments showed that these nanoparticles   are formed with various shapes. FT-IR spectroscopy revealed that   gold nanoparticles were functionalized with biomolecules that   have primary amine group (–NH2), carbonyl group, –OH   groups and other stabilizing functional groups. X-ray diffraction   pattern showed high purity and face centered cubic structure of   gold nanoparticles. Dynamic light scattering technique was used   for particle size measurement, and it was found to be about 10   nm. The rate of the reaction was high and it was completed within   5 min.
