“…The crystal film demonstrated extreme hydrophilicity in that the contact angle was too small to measure with an ordinary goniometer. Based on TEM observation, the film had high tortuosity due to the crystal grown on the plate surface (28). However, since we followed exactly the same procedure to prepare the crystal film on the TCP surface, the average surface properties can be considered consistent in all the surfaces used in this study.…”

“…Coating the surfaces of dental and orthopedic materials with biocompatible calcium phosphate apatite can elicit favorable biological and chemical responses and this can enable researchers to mimic the reactions occurring in the natural calcified tissues without compromising the bulk properties of the materials such as durability and inertness [187]. Hydroxyapatite (HA), which has many crystallographic features similar to those of the natural apatite present in bone, is a potential bone substitute, but its use is limited to low-load applications because of its poor mechanical strength.…”

Plasma-surface modification (PSM) is an effective and economical surface treatment technique for many materials and of growing interests in biomedical engineering. This article reviews the various common plasma techniques and experimental methods as applied to biomedical materials research, such as plasma sputtering and etching, plasma implantation, plasma deposition, plasma polymerization, laser plasma deposition, plasma spraying, and so on. The unique advantage of plasma modification is that the surface properties and biocompatibility can be enhanced selectively while the bulk attributes of the materials remain unchanged. Existing materials can, thus, be used and needs for new classes of materials may be obviated thereby shortening the time to develop novel and better biomedical devices. Recent work has spurred a number of very interesting applications in the biomedical field. This review article concentrates upon the current status of these techniques, new applications, and achievements pertaining to biomedical materials research. Examples described include hard tissue replacements, blood contacting prostheses, ophthalmic devices, and other products. #

“…It is important to carefully control the operating condition during the synthesis, including pH, reaction time, temperature, concentration of the reactants, as well as the proper selection of the precursor materials [26]. This is because these parameters and materials can significantly affect the composition and properties of the final HA product [27]. Table 1 briefly compares some of the common methods to synthesize HA and provides the typical operating condition and the characteristics of the synthesized product.…”

Critical-sized bone defects have, in many cases, posed challenges to the current gold standard treatments. Bioactive glasses are reported to be able to stimulate more bone regeneration than other bioactive ceramics; however, the difficulty in producing porous scaffolds made of bioactive glasses has limited their extensive use in bone regeneration. On the other hand, calcium phosphate ceramics such as synthetic hydroxyapatite and tricalcium phosphate are widely used in the clinic, but they stimulate less bone regeneration. This paper gives an overview of the recent developments in the field of bioactive nanoparticles, with a focus on nanohydroxyapatite and bioactive glasses for bone repair and regeneration. First, a brief overview of the chemical structure and common methods used to produce synthetic nanohydroxyapatite and bioactive glasses has been presented. The main body of the paper covers the physical and biological properties of these biomaterials, as well as their composites with biodegradable polymers used in bone regeneration. A summary of existing challenges and some recommendations for future directions have been brought in the concluding section of this paper.
