  • Patent number: 11970563
    Abstract: The present invention relates to a nanoparticulate composition comprising nanoparticles formed from an amphipathic block copolymer comprising a hydrophilic block and a hydrophobic block, where the nanoparticles are provided in the form of micelles, cylindrical worm structures or vesicles and the size of the nanoparticles is from 25 to 500 nm, wherein: the composition is substantially free of heavy metals and compounds comprising sulfur. Also disclosed herein is a method of forming said nanoparticulate composition by polymerization induced self-assembly (PISA) via non-transition-metal catalysed controlled radical polymerization (NTMC-CRP).
    Type: Grant
