by the Brownian motion of the active species. According to Eq. 13.10,
a higher concentration of ADT should result in a larger number of
nuclei and thus a smaller final size of superparticles. In a quantitative
analysis, superparticle size is inversely proportional to the one-third
power of ADT concentration, which is in good agreement with the
experimental results (Figure 13.6D). Furthermore, the resulting
superparticles are deformable and adhesive to each other.
