Effects of polyacrylic and polyvinyl(phosphonic acid) concentrations in a supersaturated calcium-phosphate (CaP) solution. (A) Optical density profiles of the CaP solutions containing 0–500 µg/mL of 1.8kDa polyacrylic acid (PAA1.8). The lines for all concentrations are overlapping near zero. (B) Optical density profiles of the CaP solutions containing 0–1,000 µg/mL of 6kDa polyacrylic acid (PAA6). The lines for all concentrations are overlapping near zero. (C) Optical density profiles of the CaP solutions containing 0–1,000 µg/mL 24kDa polyvinyl(phosphonic acid) (PVPA24) and a combination of PVPA24 and PASP14.
