Multiple-coated nano-particle, useful for transporting an active substance to a target cell, comprises an inner core, an inner sheath surrounding the core and an outer sheath surrounding the core and inner sheath

摘要

Multiple-coated nano-particle (1) for transporting an active substance to a target cell comprises an inner core (3) containing the active substance, an inner sheath (5) surrounding the core and at least an outer sheath (7) surrounding the core and inner sheath; where at least one of the sheath is disintegratable by selective activation. An independent claim is included for a therapeutic system comprising at least the multiple-coated nano-particle and a cell-lysing radiation dose. ACTIVITY : Cytostatic. No biological data given. MECHANISM OF ACTION : None given.
