Hydrodynamic diameter and zeta potential of SWCNTs.
| SWCNTs | In DI H2O | In BEGM | In RPMI | |
|---|---|---|---|---|
| Semi- | hydrodynamic size (nm) | 1192 ± 94 | 1683 ± 68 | 1407 ± 99 |
| zeta potential (mV) | −34.3 ±1.7 | − 8.8 ±1.0 | −7.1 ± 0.4 | |
| Metallic- | hydrodynamic size (nm) | 807 ± 229 nm | 1369 ±161 nm | 1107 ± 80 nm |
| zeta potential (mV) | −12.9 ± 0.4 | −6.9 ± 0.7 | −4.3 ± 0.2 | |
| P2- | hydrodynamic size (nm) | 880 ±175 nm | 974 ± 14 nm | 836 ± 23 nm |

The average length and diameter of the SWCNTs were assessed by UV-vis and TEM microscopy (JEOL 100 CX transmission electron microscope). The zeta potential was measured using a ZetaSizer Nano-ZS (Malvern Instruments, Worcestershire WR, U.K.). The hydrodynamic diameters in H2O, BEGM, and RPMI were determined using high-throughput dynamic light scattering (HT-DLS, Dynapro Plate Reader, Wyatt Technology).
