PBAEs facilitate efficient uptake of fluorescently-labeled DNA by GB 319 astrocytes. Different polymer structures (indicated by the numbers in each set of images) are complexed at different weight ratios (w/w) with DNA and show high Cy3 signal 4 hours after transfection. In each group, left: Phase contrast merged with Cy3 signal (red); right: Cy3 signal only. Scale bar: 200 μm. High intracellular uptake is achieved with each of these different types of polymeric nanoparticles.
