Physicochemical characteristics and drug loading properties of the prepared materials and nanoformulations.
| Materials and Formulation | Weight Loss, wt.% a |
SBET (m2/g) b | Total Drug Content c | Entrapment Efficiency, % d |
|---|---|---|---|---|
| ZnO NPs | 2.2 | 51.2 | ||
| ZnO NPs–NH2–COOH | 3.3 | 21.6 | ||
| ZnO NPs–NH2–COOH–TRP | 12.1 | 13.1 | ||
| ZnO NPs–NH2–COOH–TRP–ELG | 45.5 | 11.7 | 33.3 | 83.2 |
a Weight loss was calculated by the thermogravimetric analysis. b Specific surface area was measured using the BET technique. c,d Mean total drug loading and the entrapment efficiency were calculated from weight loss.
