TEM images of C16G0 self-assembled dendrons alone (a) and in the presence of heparin (b). In panel (b), the inset shows the full image indicating the overall nanoscale aggregate. Mesoscale molecular simulations images of C14G0 (c) and C16G0 (d) self-assembled dendrimers in the presence of heparin (heparin/binder ratio 1:2) in buffered solutions at 150 mM NaCl. The hydrophobic micellar core of is highlighted as green and blue surfaces, respectively, while the hydrophilic parts of each dendron type are shown as white sticks. Heparin chains are portrayed as orange rods, and the solvated environment is visualized as a continuous gray field. Adapted from [24] with the permission of The Royal Society of Chemistry.
