Hydroxyapatite has been used in chromatography to develop very selective isolation processes of biomolecules such as proteins, nucleic acids and antibodies.

Being a stable material up to 1000ºC hydroxyapatite is recognized as an effective catalyst for some reactions.

In pharmaceuticals and biotechnology, hydroxyapatatite has been studied as an inorganic drug carrier to treat diseases through the release of drugs and biomolecules.
