Star-shaped dendrimers synthesized by ring-opening polymerization of ε-carbobenzyloxy-L-lysine N-carboxyanhydride using generation 2nd to 5th generation dendritic macroinitiators. Depending on the generation of macroinitiator, the dendritic structure has a pre-determined number of polymeric “arms” of a rather constant chain length; reproduced with permission from Byrne et al.
