Most human body tissues are composites in nature. Using natural tissues as templates, “designer” bioactive ceramic-polymer composites are developed for tissue replacement and regeneration [
]. This biomimicking concept has now been extended into developing bioactive composites with metals or ceramics as matrices. Furthermore, with the recent emergence of tissue engineering, bioactive composite scaffolding materials are under active development [
]. The composite approach is therefore being established as one of the most important and viable ways in developing new biomaterials.
