Positively charged core-shell micelles are of interest for gene-transfer applications. Such systems may be formed by PDMAEMA-b-PLMA-b-POEGMA terpolymers. PDMAEMA is responsive to pH, ionic strength and temperature, whereas PLMA is strongly hydrophobic and POEGMA is permanently water-soluble and ensures biocompatibility. As a reference system, we investigate the simpler diblock copolymer PDMAEMA-b-PLMA as well. Detailed structural information is obtained from small-angle X-ray scattering.
