    摘要: Microspheres comprising a gelified polar core which is optionally surrounded by concentric and alternating superimposed n lipidic bilayers or n aqueous liquid layers and n gelified polar layers, n being an integer. The microspheres of the invention are obtainable by delipidation of liposomes designated as liposomes having a gelified polar core, of the type comprising at least one outer lipidic bilayer and at least one inner polar aqueous phase containing a gelified substance.
