Magnetic properties and cytocompatibility of transition-metal-incorporated hydroxyapatite.

A detailed magnetization study, along with an assessment of the cellular proliferation, has been carried out on transition-metal-doped hydroxyapatite (HA), CaM(PO)(OH), where M = Mn, Co, and Fe. In particular, a series of MnHA powder samples with an x value of 0.04 ≤ x ≤ 1.
