Biocompatible magneto‐vesicles (MVs) with multiple magnetic nanoparticles encapsulated inside were synthesized by the hydration‐sonication method in the presence of magnetic fluid with a mixture of two types of phospholipid molecules. The dimension and the size distribution of these MVs are in the same order as the vesicles synthesized in the similar method, indicating that the encapsulation does not change vesicles' properties dramatically. Releasing fluorophore molecules—carboxylfluorescein (CF) from MVs demonstrates that MVs with DOPE/DDAB layers can be a new type of magnetic carrier for biomedical applications.
