Novel nanoaggregates with peripheric superparamagnetic iron oxide nanoparticles and organic cores through self-assembly of tailor-made block copolymers

Abstract

The formation of tailor-made magnetic nanostructures is explored by self-assembly of block copolymers in the presence of superparamagnetic iron oxide nanoparticles (SPION). Depending on the nature of SPION–polymer interactions, the structures range from small-sized nanodispersions, to large nanoaggregates, to nanovesicles. The latter represent a novel arrangement into well-defined magnetic vesicles.
