Measuring Size of Light Absorbing Materials with Dynamic Light Scattering

In this application note, a ~26 nm nanogold sample was measured with two different setups of detector angle and detector position using the SZ-100V2 nanoparticle analyzer. One setup was with the 90° detector and cell center position, and the other setup was with the 173° detector and cell wall position. The absorption spectrum of the nanogold was also confirmed using a Duetta Fluorescence and Absorbance Spectrometer.
