From: Effects of size and topology of DNA molecules on intracellular delivery with non-viral gene carriers
Tapping mode atomic force microscope amplitude topography of the three DNA molecules complexed with various gene carriers. All images were captured at a scan size of 6 × 6 μm, except where noted. c-DNA without carriers [8 × 8 μm] (a), with PEI (b), PLL (c), PLL-PA (d), and Lipofectamine-2000™ (e). l-DNA without carriers (f), with PEI (g), PLL (h), PLL-PA (i), and Lipofectamine2000™ (j). pcr-DNA without carriers [5 × 5 μm] (k), with PEI (l), PLL (m), PLL-PA (n), and Lipofectamine-2000™ (o).
