Characteristics of Hb-vesicles and encapsulation procedure.

The performance of Hb-vesicles depends on the weight ratio of Hb to lipid ([Hb]/[Lipid]). This value is improved by lowering the number of bilayer membrane of the vesicle and raising the concentration of Hb in the interior of the vesicle. Maximum [Hb]/[Lipid] ratio was obtained at ca.
