ITC measurements of CholSG1 micellization gave a CMC of 8.1 µM, slightly higher than C22G1 yet still below 10 µM, a value suitable for the foreseen application of these self-assembled dendrimers as heparin rescue. TEM images of the CholSG1 nanoassemblies confirmed the formation of small spherical micelles (Figure 14b), for which DLS gave a mean average diameter of 7.5 ± 0.2 nm.
