Analytical ultracentrifugation size distributions. AUC sedimentation coefficient distributions for 66-34OT, 34-66OT, 66-34brOT, and 100MUS [34]. All four types of NPs show little difference in size. The axes of the plot are sedimentation coefficient (x) and frictional ratio (y). The former is a function of size and density; the latter is density dependent, thus a function of size and shape. The z axis displays the relative concentration of each peak
