Hydrodynamic radius (RH), polydispersity index (PDI), and zeta potential (ζ) of CH NPs loading LVF.
| NPs Sample * | RH ± S.D. (nm) | PDI % | ζ ± S.D. (mV) |
|---|---|---|---|
| Empty CH/TPP | 92 ± 43 | 21 | +25.8 ± 3.9 |
| LVF–CH/TPP2 | 85 ± 32 | 20 | +28.0 ± 3.5 |
| LVF–CH/TPP3 | 86 ± 37 | 20 | +26.4 ± 4.6 |
| Empty CH/SBE-β-CD | 134 ± 41 | 17 | +21.8 ± 5.2 |
| LVF–CH/SBE-β-CD2 | 165 ± 49 | 20 | +25.0 ± 2.2 |
| LVF–CH/SBE-β-CD3 | 159 ± 52 | 20 | +24.2 ± 4.2 |
* The amount of CH is always 10 mg. The amount of polyanion is 3 mg for TPP and 7.5 mg for SBE-β-CD. The number as subscript of NPs acronyms indicates the theoretical amount of LVF in mg (2 mg or 3 mg). LVF was added to CH solutions for the preparation of CH/TPP NPs and to SBE-β-CD for the preparation of CH/SBE-β-CD NPs. The final volume was maintained at 8 mL for all formulations.
