Summary:

This work brings a new and improving method to the determination of multimodal and polydisperse particle size distribution by Dynamic Light Scattering. In this context, we develop a Bayesian method for the estimation of the number particle size distribution from Multiangle Dynamic Light Scattering measurements. The efficiency and robustness of our method will be demonstrated through simulated and real data.
