Knowledge about the uptake mechanism and subsequent intracellular routing of non-viral gene delivery systems is important for the development of more efficient carriers. In this study we compared two established cationic polymers pDMAEMA and PEI with regard to their transfection efficiency and mechanism of cellular uptake. The effects of several inhibitors(More)
A set of polymer carriers for DNA delivery was synthesized by combining monodisperse, sequence-defined poly(amidoamine) (PAA) segments with poly(ethylene oxide) (PEO) blocks. The precise definition of the PAA segments provides the possibility of correlating the chemical structure (monomer sequence) with the resulting biological properties. Three different(More)
