Abstract

The invention relates to a nanostructured delivery system comprising at least one polymer and/or at least one lipid and at least one polymethine dye, wherein the at least one polymethine dye acting as a targeting unit brings about the targeted transport of the nanostructured delivery system into a target issue. The invention also relates to a pharmaceutical composition and the uses of the nanostructured delivery system for transporting said system and, optionally, a pharmaceutical active ingredient into the target tissue, as well for treating liver and/or kidney diseases.
