long-lasting adhesive interface between a bone replacement implant
and the surrounding tissue involves the use of bioactive materials,
such as hydroxyapatite with properties similar to natural bone.
A carbon-apatite materials, plays an essential role in forming the
chemical bond of the bioactive material to the living bones. This
carbon with apatite layer can be reproduced in vitro in SBF [9, 62].
Figure 10.23 shows the SEM images of the carbon microspheres
before and after soaking in SBF for 5 and 10 days [62].
Figure 10.23 Carbon microspheres before and after soaking in SBF for
5 and 10 days (a) and (b) before soaking; (c) and (d) after
soaking for 5 days; (e) and (f) after soaking for 10 days [62].
The carbon microspheres have size of about 2 μm (Fig. 10.23a).
The surface of the carbon microspheres is smooth (Fig. 10.23b),
and after 5 days of soaking in SBF, an apatite clusters with cotton
