Characteristics of SN-38 loaded micelles.
SN-38 loaded micelles | D/P ratioa | DLE (%)b | DLC (%)c | Mean size/nmd |
---|---|---|---|---|
SN38/P-I | 1/10 | 47.3±1.6 | 4.52 | 51 ±19e |
SN38/P-II | 1/10 | 92.3±4.3 | 8.45 | 34 ±10 |
SN38/P-III | 1/10 | 72.4±3.9 | 6.75 | 156 ± 73 |
SN38/P-IV | 1/10 | 92.9±1.9 | 8.50 | 34 ±11 |
D/P ratio= weight of SN-38/weight of polymer.
Drug (SN-38) loading efficiency (%)= (weight of SN-38 in the micelles/weight of total SN-38 in the loading solution) ×100. Data were obtained from triplicate experiments.
Drug loading content (%)= weight of SN-38/(weight of SN-38+ weight of polymer) ×100.
Determined by dynamic light scattering (DLS).
After remove precipitation by filtration.
