In situ approaches to establish colloidal growth kinetics.
A technique based on the back scattering phenomenon of dynamic light scattering has been employed to monitor the kinetics of gold and platinum metal nanoparticle growth and silver nanoparticle oxidation as well as in the determination of particle sizes ranging from 1 to 200 nm in diameter. The systems were chosen to examine the applicability of dynamic light scattering to nanoresearch over a broad range of sizes as well as both metallic and nonmetallic systems. The advantages of this instrumentation over traditional instruments such as X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) have been highlighted.
