The authors present a high yield, scalable method for synthesis of asymmetric nanoparticles with aspect ratios of up to 1.8. They use core shell particle consisting of a polystyrene core with a random copolymer of styrene and trimethoxysilylpropylacrylate (TMSPA) grown on the outside as a shell. The polystyrene can be swelled with toluene or styrene monomer. At sufficiently high swelling, the core will breach through the copolymer shell (see figure xxx).
