| Resumo | The development of porous materials for the sustained three-dimensional growth of cells, such as scaffolds composed of vertically-aligned multi-walled carbon nanotubes (VACNT) is of particular interest in regenerative medicine and tissue engineering, because they can be potentially tailored to mimic the natural extracellular matrix in terms of structure, chemical composition and mechanical properties [1]. Template-induced hydroxyapatite (HA) has broad prospects in the applied fields of regenerative medicine and bone repair. In this work it was evaluated the bioactivity properties of superhydrophilic VACNT/HA composites. The VACNT films were produced as a thin film, using a microwave plasma chamber at 2.45GHz on Ti substrate (10 mm2) which Ni catalyst [2]. Superhydrophilic VACNT scaffolds were obtained by the incorporation of oxygen-containing groups using a pulsed-direct current plasma reactor with an oxygen flow rate of 1 sccm, at a pressure of 85 mTorr, -700 V and with a frequency of 20 kHz [3]. The fabrication of VACNT/HA composites was performed with a direct electrodeposition of the thin HA films on the VACNT scaffolds using Ca(NO3)2.4H2O + (NH4).2HPO4 electrolyte applying a constant potential of -2.0 V for 30 minutes, with the solution temperature maintained at 80 oC. The bioactivity of superhydrophilic VACNT/HA composites was investigated using simulated body fluid (SBF) similar to physiological condition and products tailored to mimic natural bone. The XRD, Raman spectroscopy, SEM and EDX, analysis were employed to investigate the structural characteristics, semi-quantitative analysis and morphology on the formation of crystalline HA on VACNT scaffolds before and after soaking with SBF. The formation of a thin homogeneous and highly crystalline film, with excellent properties of bioactivity was observed. Coating HA material on VACNT-template provides a way of combining the superior mechanical properties and chemical stability of the CNTs with the excellent biochemical properties of HA. | |||
