Application Note: Gold and Silver Coated Nano Particles: Characterizing Coating Thickness for Nano-scale Drug Delivery
29 July 2013

This application note describes how, using the technique of Differential Centrifugal Sedimentation (DCS), peaks in particle size distributions for both the coated and uncoated particles can easily be separated and resolved; making this technique an ideal characterization tool, enabling coating thickness to be measured and the coating process monitored.
