Blandin, et al. Chapter 2 Terminology for catalysts and methods defines essential terms relating to this thesis. Although zeta potential is an intermediate value, it is sometimes considered to be more significant than surface potential as far as electrostatic repusion is concerned. Its integrated wet and dry dispersion modes, built in video camera and short optical path make it the most versatile instrument available anywhere. For ongoing production then,. This is a widely used particle sizing technique for materials ranging from hundreds of nanometers up to several millimeters in size.

Thankfully, this is not the beginning of a lesson on quantum physics; instead, it is the basis for potentially designing targeted clinical trials in nanomedicine, by knowing if a tumor is likely to respond to a particular therapeutic nanoparticle. When in solution, macromolecules are buffeted by the solvent molecules. Fennessy et al. Dynamic light scattering (DLS) measures time-dependent fluctuations in the scattering intensity arising from particles undergoing random Brownian motion.
