Effect of 4-HR on thickness and density of poly(lactic-co-glycolic acid) (PLGA) films.
| 4-HR Content (mg/mg PLGA) | Thickness (µm) | Density (g/cm3) |
|---|---|---|
| Neat PLGA | 75 ± 18 a | 0.94 ± 0.06 a,b |
| 0.03 | 81 ± 7 a | 0.83 ± 0.12 a |
| 0.06 | 83 ± 19 a | 0.81 ± 0.07 a |
| 0.1 | 66 ± 12 a | 0.99 ± 0.08 a,b |
| 0.15 | 64 ± 14 a | 1.10 ± 0.17 b |
| 0.3 | 67 ± 8 a | 1.06 ± 0.13 b |
| 0.5 | 92 ± 15 a | 1.08 ± 0.10 b |
Mean values ± standard deviation. Different superscript letters in the same column represent significant differences (a,b p < 0.05). Groups with dual letters (a,b) are not statistically different from other groups marked with a or b.
