Polarization of porous and dense hydroxyapatite for enhanced bone formation

Abstract

Recently, we have proved that hydroxyapatite (HA) bioceramics are excellent electrets with an outstanding chemical and biological effects. These elctrets can be prepared by electrical polarization. Due to the electrical treatment, surfaces are electrically charged, depending on the direction of applied dc field. In this report, we will show the electroceramic properties of HA with the interesting electrical properties, then their biological effects are demonstrated in the solidification phenomena in a simulated body fluid (SBF) as well as in vivo affinity.
