Composite of nanostructured hydroxyapatite and polymer

Microparticles formed by nanostructured hydroxyapatite crystals and biopolymers. Hydroxiapatite (HA) is one of the most biocompatible ceramics because it is similar to the mineral constituents of human bone and teeth. This composite are interesting biomaterial for medical applications, especially for bone replacement. The colors were obtained using the software FEI Company
