These colloids were used to form close-packed colloidal clusters using a Salting Out-Quenching technique developed by Yake et al. [1] By analysing optical microscopy images, the cluster size distribution was determined. Finally, the colloidal clusters were swollen with toluene or monomer to permanently fuse the colloids together. During the swelling process, the particles folded back into close-packed structures to minimise the second moment of the mass distribution.Show less
