Total porosity of freeze dried scaffolds measured by pycnometer and micro-computed tomography (µ-CT) data analysis. Porosity measured by pycnometer showed a statistically significant (** p < 0.005) difference between values of PA compared to AGG2 and AGG3.
| Scaffold type | Porosity measured by pycnometer (n = 5) (%) | Porosity measured by µCT image analysis (n = 4) (%) |
|---|---|---|
| PA | 79.7 ± 1.2 | 66.9 ± 3.4 |
| AGG2 | 69.5 ± 1.2 ** | 60.8 ± 2.8 |
| AGG3 | 69.3 ± 1.0 ** | 62.3 ± 2.3 |
