Hydroxyapatite for biomedicine and drug delivery

Abstract

Hydroxyapatite (HA) is a member of the calcium phosphates family (Table 1) and like the other ones is known as a bioceramic with specific advantages raise from chemical similarity to the mammalian inorganic structure. In comparison to other CaPs, HA has highest thermodynamic stability and solubility (after Fluorapatite) in physiological conditions.
