Figure 3. AFM images of (hk0)- planes of FAP: (a) before immersion; (b) after immersion in CaP-sol containing 0.4 mg/mL rH174, showing amelogenin nanospheres; (c) after immersion in CaP-sol containing 1.6 mg/mL rH174, showing organization and alignment of nanoparticles (50 nm) in short string-like patterns approximately parallel to the c-axis of the underlying FAP crystal; and (d) after immersion in CaP-sol containing 1.6 mg/mL rH174, showing increased height of layers grown on (001)- planes (130 nm) vs. (hk0)- planes (40 nm).
