ENP | Hydrodynamic Size (nm) | Concentration (Number of Particles/mL) |
Oxidative Potential (A.U.) * |
Effective Density (mg/mL) |
---|---|---|---|---|
SnO2 | 455.5 ± 17.98 | 2.70 × 108 | 4958 | 6.7 |
ATO | 688.5 ± 97.80 | 12.28 × 108 | 4081 | 17.4 |
CeO2 | 305.6 ± 79.72 | 8.07 × 108 | 4806 | 1.5 |
ZrO2 | 406.0 ± 1.79 | 22.05 × 108 | 3408 | 3.5 |
Data are presented as mean ± SD. Hydrodynamic size was measured by Dynamic Light Scattering (DLS). Concentration was determined by Nanoparticle Tracking Analysis (NTA). Oxidative potential was measured by Electronic Spin Resonance (ERS). A.U.: arbitrary units. * Negative control (ultrapure water) = 3191 A.U.; Positive control (DOFA) = 48,041 A.U.
