| Hydrogel/Film Code |
NYS (mg) |
PRO (mL Solution/mg Solid Compound) |
Films Thickness (µm) |
|---|---|---|---|
| CS-LA | - | - | 49 |
| CS-NYS | 15 | - | 53 |
| CS-PRO | - | 0.30/90 | 210 |
| CS-NYS-PRO1 | 15 | 0.15/45 | 166 |
| CS-NYS-PRO2 | 15 | 0.30/90 | 220 |
* all hydrogel formulations also contain 0.3 g CS (in 10 mL 2% LA solution) and 0.4 g Gly; the films were obtained by hydrogel drying and each formulation has a composition identical to the corresponding hydrogel, without water.
