Physical Properties of Multilayer Titania Nanofilms
| (PAH/TALH)n layers | 0 | 1 | 3 | 5 | 10 |
|---|---|---|---|---|---|
| Surface roughness (nm)a | — | 1.39 | 4.80 | 7.30 | 5.09 |
| Phosphopeptide enrichment | None | Weak | Weak | Strong | Strong |
| Phospholipid mobilityb | 100% (3.0 μm2 s−1) | 63% (1.9 μm2 s−1) | 0% | 0% | 0% |
a
Surface roughness is provided as the root mean square (rms) of the height profile over a 10 μm2 area, measured by AFM.
b
Mobilities of supported lipids are provided as the mobile fraction (β) in percent of total lipids bound to the substrate. If lipids were found to be mobile, then their diffusion coefficients (D) were also provided.
