“…Commercially available magnetic carboxymethyl‐dextran coated magnetite (Fe 3 O 4 ) NPs (fluidMAG‐CMX, Chemicell, Berlin, Germany) have been embedded in the aqueous core of extruded soybean‐phosphatidylcholine (SPC), (Phospholipon 90G; Phospholipid, Cologne, Germany) liposomes to form the so‐called MLs. MLs were prepared by thin film hydration method followed by extrusion as reported in [Petralito et al, ]. Briefly, a dry SPC film (60 mg) was hydrated with 10 ml of 4‐(2‐hydroxyethyl)piperazine‐1‐ethanesulfonic acid, (Sigma–Aldrich, Milan, Italy) buffer solution (HBS) 10 mM, pH 7.4, containing both magnetic NPs (number of NPs to liposome vesicle ratio was 2:1) and 20 mM 5(6)‐carboxyfluorescein (CF).…”
