Synthesis, aggregation and responsivity of block copolymers containing organic arsenicals

Block copolymers containing an organic arsenical (AsAm) have been synthesised by aqueous SET-LRP. The block copolymers are pH and thermoresponsive, forming nanoparticles in aqueous solution. Under reductive conditions the particles are stabilised through the formation of As-As bonds and stability can be tuned as a function of the AsAm monomer feed.
