The formation of phase pure HAP nanorods was confirmed by FTIR and XRD studies [83]. The SEM morphological evaluation evidenced the formation of uniform size-distributed HAP nanorods, when tamarind extract was used as green template (Fig.…”

Bioceramics are the materials which can enhance the quality and longevity of human life. Hydroxyapatite (HAP) is a readily considered bioceramic material for artificial bone substitution in biomedical field due to its compositional resemblance to the bone mineral and very good biocompatiblity. Recently, HAP has attracted significant interest in drug delivery and bone tissue engineering applications. The human cortical bone consists of biological HAP which is found within collagen as nanodimensional crystalline aggregates. There has been enormous effort in developing bioactive synthetic ceramics that could closely mimic the fine and complex structure of human bone. Though HAP is highly biocompatible and bioactive, it possesses poor mechanical properties. In order to overcome this drawback, attempts are made toward the synthesis of mineralized HAP. Several methodologies have been investigated and developed for the synthesis of pure and substituted HAP. Modern research deals with novel HAP nanostructure formulations with properties closer to those of living bone, aiming at improved and more effective biomedical applications. This chapter presents the facile and cost-effective synthesis methods of pure and substituted HAP nanoparticles such as sol-gel approach, hydrothermal techniques, etc., toward effective biomedical applications.

“…In a typical experimental procedure for the green synthesis of HAP [37,38], the apple extract powder of 1 wt% was subsequently dropped into 0.5 M aqueous CaCl 2 Á 2H 2 O solution under constant stirring. The above mixture was subjected to continuous stirring for 1 h and to this, 0.3 M aqueous solution of H 3 PO 4 was also added drop wise under stirring.…”

“…Further, the green template method proves to be the best method rather than the chemical and physical methods, as it is economical, environment friendly, easily scaled up for large scale synthesis and in this method there is no need to use high pressure, energy, temperature and toxic chemicals. Very recently Gopi et al, successfully synthesized HAP particles using sucrose, tartaric acid and pectin derived from the natural sources, as green templates [36][37][38].…”

Hydroxyapatite (HAP) forms the main inorganic component of natural bone and hence has been widely use in implant applications. Ionic substitutions in apatite also gains enormous interest during the recent years due to the crucial role played by these elements in the biological process. In this context, the least investigated elements namely lanthanum (La3+) and praseodymium (Pr3+) have been selected as a potential substitutions in apatite. The results from the analytical techniques confirm the phase purity of the HAP and its ability holds the substitutions at its lattice. Morphological analysis unveils the presence of agglomerated spheroids notwithstanding the ion concentration of substituents. EDX spectra affirm the presence of La and Pr alongside the determined Ca/P atomic ratio of 1.67. La3+ and Pr3+ presence envisaged the good antibacterial efficiency against the tested microbes and further demonstrated the biocompatibility nature from the cytotoxicity analysis.
