| Concentration (mg/ml dH2O) | dH (nm) | PdI | ζ (mV) | Conductance (mS/cm) |
|---|---|---|---|---|
| 0.67 | 222 ± 4 | 0.24 ± 0.01 | −17.4 ± 1.9 | 0.02 ± 0.0 |
| 6.7 | 241 ± 5 | 0.37 ± 0.02 | −18.6 ± 0.9 | 0.07 ± 0.01 |
| 33.3 | 388 ± 29 | 0.51 ± 0.08 | −9.7 ± 0.6 | 0.15 ± 0.01 |
Data are mean ± SD, n = 3. dH, hydrodynamic diameter, PdI, polydispersity index, ζ, zeta potential.
