Paper Abstract

High-sensitivity low-coherence dynamic light scattering (LC-DLS) is a powerful technique for measuring particle sizes in dense suspensions without the need for dilution. We have developed an LC-DLS system with a single-mode (SM)- fiber probe system and small container that can be used to hold samples of 10μL in volume. The system can be applied to lysozyme of a few nm in diameter. We have developed an angle-resolved SM-fiber probe system that is able to identify particle motion type and we verified our design by identifying the diffusion modes of particles in a polystyrene suspension.
