Reported here is a new class of PICsomes (vesicles formed by polyelectrolyte complexation) in which the anionic/neutral diblock copolymer replaced an anionic, reversible, supramolecular based on metal-ligand coordination. This forms exclusively inside wall assembly, and therefore self-adjusts its length to that cationic block provided. Moreover, coordination polyelectrolytes introduce tunable properties functions associated with specific metal. As proof-of-concept Mn-based were prepared display high magnetic relaxivity, as well enhanced contrast vitro resonance imaging tests. The simplicity our approach, together derived from metal ions, demonstrates robust strategy for preparation variety well-defined structures properties.
