This article investigates the self assembly of gold nanoparticles that are coated with amphiphillic block copolymers (PS-PEO). These amphiphillic colloidal molecules (ACMs) self assemble into well defined vesciles and tubules when rehydrated in water depending on the relative size of the gold nanoparticles and the size of the PS block. The authors found that when R0/dAu < 0.5, vesicle formation was favorable whereas when R0/dAu = 0.5, tubules were favored. When R0/dAu > 0.5, the AMCs precipitated and could not be rehydrated.
