Hydroxyapatite–titanium dioxide (HAp-TiO2) nanohybrid composite was coated on Ti–6Al–4V and Ti–13Nb–13Zr substrates by electrophoretic deposition. Coating surface characteristics and biocompatibility were analysed using X-ray photoelectron spectroscopy, water contact measurement, scanning electron microscopy and fluorescence microscopy. The results indicated high degree of crystallinity and densely packed crack free morphology of the coating. The coated substrates displayed lower contact angle (Ti–13Nb–13Zr, 17·4°; Ti–6Al–4V, 22·2°) than the controls (Ti–13Nb–13Zr, 80·8°; Ti–6Al–4V, 72·6°). The cytocompatibility of the coated substrates was determined by staining the human dermal fibroblast cells with 4′,6-diamidino-2-phenylindole and imaging under fluorescent microscope. Both SEM and florescence microscope images showed comparatively enhanced cell adhesion on coated Ti–13Nb–13Zr and Ti–6Al–4V than the uncoated substrates. This difference could be attributed because of the higher wettability of Ti–13Nb–13Zr. Hence, this study provides evidence that the coating provided a better surface property for adhesion of human dermal fibroblast cells. [ABSTRACT FROM AUTHOR] |
