Quartz crystal microbalance in open cell mode showing relationship between adsorbed hydrated mass (calculated from Δfrequency) of mfp-3f, mfp-3s and COL1A1 to a TiO2 surface and injection number. Injection number refers to the incremental addition of mfp-3 (Cmfp-3 = 20μg/ml) or COL1A1 (CCOL1A1 = 25μg/ml) aliquots, which are indicated by arrows for each protein. Note that COL1A1 did not adsorb to TiO2. Adsorption solution conditions were 0.1 M sodium acetate buffer, pH 3.0 and 0.25 M KNO3 at room temperature and pressure. For dissipation changes, see supporting data.
