Structural characterisation of parotid and whole mouth salivary pellicles adsorbed onto DPI and QCMD hydroxyapatite sensors

- Comparison of structural differences between parotid and whole mouth salivary pellicles via QCMD (acoustically) and DPI (optically).
- The first time hydroxyapatite coated DPI sensors have been used to measure salivary protein adsorption.
- Data presented help to further define the mechanisms leading to the multi-layered structure of the salivary pellicle.
- Demonstrates that salivary composition has an important effect on the structural properties of the adsorbed pellicle.
