Ruiz-Pérezet al.report the nanoscale detection of metal-labelled copolymers in patchy polymersomes.
The synthesis of polymersome-forming block copolymers using two different synthetic routes based on Atom Transfer Radical Polymerisation (ATRP) and Reversible Addition Fragmentation chain Transfer (RAFT) polymerisation is reported.Functionalisation with 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) allowed the block copolymer chains to be labelled with electron-dense metal ions (e.g.indium).The resulting metal-conjugated copolymers can be visualised by transmission electron microscopy with single chain resolution,hence enabling the study of polymer/polymer immiscibility and phase separation on the nano-scale.
