(a) Integrated SAXS curve measured from self-assembled dendrimers C14G0 (black upper curve) and C16G0 (red lower curve) in the presence of heparin. The insets show the corresponding 2D diffraction patterns. (b) Quadratic Miller indices of assigned reflections for face-center cubic (fcc) structures as function of measured q-vector positions for indexed peaks, related with heparin-bound C14G0 (black symbols) and C16-G0 micelles (red symbols). (c) (Top row) A crystalline area for C14G0 (top left; inset: Fast Fourier transform) and a line profile analysis (top right) along the red double pointed arrow shown in the top left panel. (Bottom row) Filtered inverse Fourier transform from selected Fourier components for the C14G0 (left), overlay of the image and the fcc unit cell (center), and model of the unit cell with key dimensions (right). The micelles are shown in yellow using a reduced Dm value for clarity. Adapted from [26] with the permission of The Royal Society of Chemistry.
