The particles are chemically formed in such a way as to enable a high intracellular absorption into the cells. The encapsulation requires no direct binding between nanoparticles and the therapeutically active substance. The encapsulation enables an increased efficiency of the substance with a simultaneously low systemic toxicity, therefore an increase in efficiency with simultaneous reduction of side effects.
