32. One may note that nanoparticle aggregates started to form at much lower concentrations as shown in Figures 1 and 2. Thus the selection of this concentration as CMC is somewhat arbitrary, but it may represent an upper limit. Experimentally we first prepared the nanoparticles at 1 mg/mL, and then diluted the solutions to varied lower concentrations (0.004 to 0.4 mg/mL). The fact that we observed drastic variation of the dimensions of the nanoparticle aggregates suggests that the nanoparticle aggregates dissembled at concentrations below the CMC value, and the nanoparticle assembly was driven by thermodynamics rather than kinetics, analogous to conventional surfactant molecules.
