“…On continuation of the previous work, i.e., synthesis of n-HAP using glycine as template, as discussed in the section "Amino Acid Soft Solution Freezing Method," Gopi et al [81] have reported the sizecontrolled synthesis of n-HAP using mixed hollow sphere template material with the aid of ultrasonic irradiation technology. The hollow sphere template used in this method was achieved using the mixture of glycine and acrylic acid (GLY-AA).…”

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.

“…Therefore, a synthetic routes with advantages oflow cost and efficiency is still need to be investigated. In recent years, ultrasonic method is become a novel technique to obtain nanomaterials [9]. Ultrasonic method can effectively reduce the particle aggregation via cavitation phenomenon that is the formation, growth and severe collapse of cavitation bubble in the liquid medium at the action of ultrasound [10].…”

Abstract. In this paper, to develop a new method to rapidly synthesize hydroxyapatite nanoparticles as a controlled release carrier, sonochemical method was used to prepare nano-hydroxyapatite (nHAP) without any surfactant and used calcium nitrate tetrahydrate and diammonium hydrogen phosphate as source materials. The composition of obtained hydroxyapatite nanoparticles was determined by X-ray powder diffraction (XRD) and fourier transform infrared spectra (FT-IR). The morphologies and microstructure were observed by transmission electron microscope (TEM). Pure nHAP was successfully synthesized by ultrasonic method without any surfactant. The particles shows not obvious reunion and display rod-shaped structure with length of about 40-120 nm and width of about 30 nm.
