The invention relates to a carrier and targeting system for the intracellular delivery and triggered release of a siosome- and/or siosome-liposome-entrapped or encapsulated active substance or therapeutic agent. The invention further relates to the targeted release and delivery of doxorubicin, cis-platin, carbo-platin and/or oxali-platin, characterized in that one or more anionic lipids, such as cholesteryl hemisuccinate residues, cardiolipin and/or their derivatives and/or other anionic groups, are covalently linked to the silicone central atom of the silanes, sugar silanes and/or amino-sugar silanes. The invention further relates to the use of cationic lipids that are covalently attached to the silicone central atom of the silanes. The invention also relates to a method for preparing such carrier and targeting systems and methods for their administration.
