(a) QCM-D data (markers) and corresponding fits to the Voigt model using overtones 3rd, 5th, an 7th (solid lines) for a representative experiment where human whole saliva (HWS) was adsorbed on silica surfaces, rinsed with PBS buffer, exposed to C₁₂E₅ in PBS solution and finally rinsed with PBS buffer again. (b) Adsorbed mass calculated from fitting the data in (a) to the Voigt model. (c) QCM-D data (markers) and corresponding fits to the Voigt model using overtones 3rd, 5th, an 7th (solid lines) for a representative experiment where human whole saliva (HWS) was adsorbed on silica surfaces, rinsed with PBS buffer, exposed to a CAPB in PBS solution and finally rinsed with PBS buffer again. (d) Adsorbed mass calculated from fitting the data in (c) to the Voigt model.
