Most previous reports monitoring the self-assembly of block copolymers derive kinetics from ensemble properties: For example, light scattering can be employed to report on the average size of CDSA micelles. However, these ensemble methods are insensitive to heterogeneity in the growth of individual nanoparticles and provide no direct information on particle morphology. Given the uniform complex hierarchical structures desired by CDSA, this ensemble averaging is a significant drawback in understanding and quantifying growth mechanics.
