Dynamic light scattering based optical microrheology in non-aqueous solutions

摘要

A micro-rheological measuring method comprises providing a complex fluid sample 15 that includes a non-aqueous hydrophobic solvent, embedding hydrophobic probe particles 17 in the complex fluid sample, illuminating the sample with coherent light 12, detecting 20 scattered photons from the scattering of the coherent light by the hydrophobic probe particles in the complex sample fluid, performing a correlation operation on a detection signal representative of the detected scattered photons, and deriving at least one theological property of the complex sample fluid from results of the correlation operation.
