Size characteristics of microbubbles used in this study.
| MB size class | Mean (μm)* | Median (μm) | Mode (μm) | |
|---|---|---|---|---|
| 2-µm | Accusizer | 1.53 ± 0.16 | 1.44 ± 0.06 | 1.70 ± 0.19 |
| Multisizer | 1.80 ± 0.02 | 1.73 ± 0.03 | 1.74 ± 0.12 | |
| 4-µm | Accusizer | 3.50 ± 0.25 | 3.67 ± 0.15 | 4.20 ± 0.20 |
| Multisizer | 4.07 ± 0.09 | 4.13 ± 0.05 | 4.33 ± 0.07 | |
| 6-µm | Accusizer | 5.58 ± 0.28 | 5.67 ± 0.22 | 6.36 ± 0.79 |
| Multisizer | 6.24 ± 0.11 | 6.36 ± 0.05 | 6.46 ± 0.14 |
*Measurements were made for n ≥ 3 batches, with at least 3 measurements per batch. All size groups were found to be significantly different from each other for both sizing systems (p < 0.01).
