The hydrodynamic radius sizing of nanoparticles in dense polydisperse media is investigated by low-coherence dynamic light scattering (low-coherence DLS). A conventional CONTIN algorithm is used to analyze the amplitude autocorrelation function of single scattered light detected preferentially from multiply scattered light. The great potential of the low-coherence DLS is confirmed experimentally for the noninvasive characterization of the hydrodynamic and structural properties of dense polydisperse media. As a result, the new particle-sizing technique for dense polydisperse media based on the low-coherence DLS is established in this study.
