Figure 2: The size distribution of different SMA-ZnPP micelles.Three independent measurements were done for each loading at the concentration of 1 mg/ml in DW within 10 min after dissolution. The average size of A. SMAZnPP 15% is 54.6 nm; B. SMA- ZnPP-GLU 15% is 54.7 nm; and C. SMAZnPP30% is 62.0 nm.
