Abstract

Atomic force microscopy (AFM) has been used to image the surface atomic structure of hydroxyapatite [Ca10(PO4)6 (OH)2], HA, and brushite [CaHPO4 · 2H2O], DCPD. Compared to HA, the surface of DCPD was found to be much less complex. Identification has been made of one crystal plane of DCPD that has atoms commensurate with those of one of the observed crystal planes of HA.
