Schematic illustration of the synthesis of amphiphilic gold nanocrystals grafted with polymer brushes. (a) ‘Grafting to’ amphiphilic diblock polymers ended with a thiol end group. (b) Tandem ‘grafting to’ (co-adsorption of hydrophilic homopolymers and ATRP or ROP initiators) and (c)‘grafting from’ (surface-initiated ATRP or ROP polymerization) hydrophobic polymers. The hydrophilic polymer brush is in green and the hydrophobic polymer brush is in blue.
