Effect of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and phospholipase A2 (PLA2) on surface properties of silica materials

- Modification of silica materials by phospholipid and enzyme.
- Wettability of DPPC monolayer before and after enzyme action.
- Effect of kind of solid support on surface free energy of the lipid layer.
- Changes in the hydrophobic/hydrophilic character of DPPC monolayer caused by enzyme.
