| Concentration (mg/ml dH 2 O) | d H (nm) | PdI | ζ (mV) |
|---|---|---|---|
| 0.66 | 144 ± 4 | 0.20 ± 0.03 | −18.5 |
| 1 | 154 ± 21 | 0.24 ± 0.07 | −18.7 |
| 10 | 354 ± 3 | 0.46 ± 0.03 | −16.5 |
Data are mean ± standard deviation, n = 3.
dH, hydrodynamic diameter, PdI, polydispersity index, ζ, zeta potential.
