Quartz crystal microbalance for comparison of calcium phosphate precipitation on planar and rough phospholipid bilayers

- The planar phospholipid bilayers were fabricated on bare quartz crystal.
- The rough phospholipid bilayers were fabricated on titania-modified quartz crystal.
- Rough phospholipid bilayers exhibited a higher deposition rate of calcium phosphate.
- The negative potential was more favorable for calcium phosphate precipitation.
