ARC Centre of Excellence in Exciton Science School of Chemistry, University of Melbourne We are impressed with the fast scan, user friendly modular design and high throughput of Agilent Cary 3500 UV-Vis. In particular, the great temperature ramping rate and sensitivity makes our work easier. Our project uses UV-Vis to research how temperature affects the scattering properties of gold nanoparticles coated in PNIPAM polymer. As temperature increased over the 30 – 40 °C range, the polymer collapses and the particles aggregate; we are interested in understanding the dynamics of these processes. Wavelength scans at different temperatures, and thermal gradient scans are used to partially characterize these processes. We also do these measurements over a range of pH, salt concentrat View More
