The success of the emerging bio-nanotechnological approaches to solve cross-cutting problems in cancer relies on the sophistication of tailored nanovectors to increase the efficacy per dose of any therapeutic agent. In our approach we endow agents comprising the vector as a multifunctional, organic carrier in a bioinspired design with the ability to realize the integration of targeting units, drug molecules. The increasing demand of imaging probes correlated with efficacy testing of drug carriers has opened up a new playground for polymeric architectures. As a result, the encapsulation of imaging reagents, or chromophores especially in 3-D, also vitalized the investigation of electronic properties through site isolation effects of electroactive entities in well-defined nanoobjects. The precise correlation of molecular structures with macroscopic properties such as quantum efficiency, thermostability, photostability and processability, is one of the most important, but as yet not fully resolved challenges in the investigation and exploitation of polymeric materials.
