OVERVIEW
Hydroxyapatite (HA) is a calcium phosphate mineral(Ca10(PO4)6(OH)2) which is the main constituent in bone and teeth.HA is known for its special proper-ties, especially when in contactwith living tissue. HA's bioactivity is ad-vantageous in a range ofapplica-tions, such as bone implants and stents. Due to HA’s uniquesimilar-ity to the hard tissues found in bio-logical systems, it iswidely used as reference material whenever inter-actions betweenhard tissues and biological species are of interest. Q-Sensecollaborates with the company Promimic that has devel-oped aproprietary method to coat materials with nanocrystallineHy-droxyapatite having high stability and smoothness, calledPromimic HANANO.
