Bonelike apatite formation utilizing carbon nanotubes as template.
Template-induced hydroxyapatite (HA) has broad prospects in the applied fields of regenerative medicine and bone repair. HA thin coatings have been deposited on vertically aligned multiwalled carbon nanotubes (CNTs) via the high-temperature radio-frequency (rf) magnetron sputtering deposition technique. Simulated body fluid (SBF) solution has been used to soak and incubate the HA/CNTs nanocomposites at 37 degrees C. SEM, EDS, XRD, and FTIR characterizations revealed bonelike apatite formation on top of HA/CNTs composites. Coating HA material on well-aligned CNT-template provides a way of combining the superior mechanical properties and chemical stability of the CNTs with the excellent biochemical properties of HA.
