intensities, I600 / I540, decreases. About 90% of cargo dextran was remained within liposomes after the immobilization/release procedure on AAO membranes (Figure ). Similarly, a larger cargo, 40 kDa dextran, was found to be largely kept inside the liposomes as well (Figure and Table ). These results encourage the use of AAO membranes as a storage of drug or biomolecule-loaded liposomes with a toward the drug delivery system applications.
