title: Synthesis of multiple shapes of gold nanoparticles with controlled sizes in aqueous solution using ultrasound.
abstract: Effects of concentration of stabilizer (sodium dodecylsulfate: SDS) and ultrasonic irradiation power on the formation of gold nanoparticles (Au-NPs) were investigated. Au-NPs with multiple shapes and size were synthesized by controlling the concentration of stabilizer and ultrasonic irradiation power. The shapes and size of Au-NPs were controlled by changing either the ratio of Au(III) ion/SDS or the power of ultrasonic irradiation. The multiple shapes and size distribution of Au-NPs are dependent on not only the ratio of Au(III) ion/SDS but also ultrasonic irradiation power. The sonochemically synthesized Au-NPs were characterized by TEM and UV-vis spectroscopy.
