“…Further, it is also well known for its good osteoconductivity, biocompatibility, and bioactivity. Nevertheless, synthesized HA (Figure 3) does not possess the specific trace ions which are normally found in the chemical structure of the osseous tissue that aids in bone formation, and, therefore, it possesses inferior bone regeneration [14,15]. In this regard, Bassyouni et al reported that, by increasing the degree of crystallinity of HA and decreasing its grain size, the bioavailability of the material would be improved.…”

Bone tissue engineering has attracted great interest in the last few years, as the frequency of tissue-damaging or degenerative diseases has increased exponentially. To obtain an ideal treatment solution, researchers have focused on the development of optimum biomaterials to be applied for the enhancement of bioactivity and the regeneration process, which are necessary to support the proper healing process of osseous tissues. In this regard, hydroxyapatite (HA) has been the most widely used material in the biomedical field due to its great biocompatibility and similarity with the native apatite from the human bone. However, HA still presents some deficiencies related to its mechanical properties, which are essential for HA to be applied in load-bearing applications. Bioactivity is another vital property of HA and is necessary to further improve regeneration and antibacterial activity. These drawbacks can be solved by doping the material with trace elements, adapting the properties of the material, and, finally, sustaining bone regeneration without the occurrence of implant failure. Considering these aspects, in this review, we have presented some general information about HA properties, synthesis methods, applications, and the necessity for the addition of doping ions into its structure. Also, we have presented their influence on the properties of HA, as well as the latest applications of doped materials in the biomedical field.

“…Up to now, the reports on Ta doped ZnO are quite a few, and they only focus on materials' electrical, thermal, and optical properties. [26][27][28][29][30][31][32] Some other reports study antibacterial or catalytic properties, 33,34 and there are very few research reports on the photocatalytic activity of Ta-doped ZnO. 16,17 In a study by the author group B.-L. Guo with colleagues, Tadoped ZnO nanomaterials were prepared by a modied Pechini-type method, and their antibacterial ability was studied with some Gram-positive bacteria Bacillus subtilis (B. subtilis) and Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) Gram-negative and Pseudomonas aeruginosa (P. aeruginosa).…”
