“…Microwave heating generates heat within the samples, reducing reaction time and increasing nucleation rate and growth [95,98,[174][175][176]. HAp can be obtained with differentiated structures, such as nanostructured mesoporous microspheres [177], mesoporous lozenges [178], and hollow microspheres [45], using various organic additives, such as amino acids [179,180], surfactants [160,[180][181][182][183][184][185], or natural origin substances [186,187]. The combination of biochemical and hydrothermal procedures by incorporating an aqueous medium into the system can accelerate the kinetic processes that normally limit the rate of reaction in a conventional mechanochemical method.…”

“…HAp has been obtained in form of nanoblasts [182,183,188], nanofibers [189][190][191], nanowires [184], and nanotubes [151,186]. These structures are said to be 1D and have a size of ≤100 nm in at least one of their dimensions, resulting in high surface activity and an ultrafine structure, similar to the mineral of hard tissues [41].…”

A brief review on hydroxyapatite production and use in biomedicine

Hydroxyapatite (HAp) is a bioceramic widely studied due to its chemical similarity with the mineral component of bones. Besides, it is biocompatible, bioactive and thermodynamically stable in the body fluid what poses it as an attractive material for a wide range of applications in the biomedical field. Several efforts have been focused on the synthesis of particles of this material aiming to the precise control of size and morphology, porosity and surface area. HAp is widely used as an implant for bone tissue regeneration, as a coating for metallic implants and in a drug-controlled release. In this sense, the objective of this review is to gather information related to HAp, providing readers with information about synthesis methods, material characteristics and their applications.

Human tooth enamel has tightly packed c-axis-oriented hydroxyapatite (HAP: Ca10(PO4)6(OH)2) nanorods with high elastic modulus. Fabrication of an enamel architecture in vitro supports the repair of teeth using HAP; however, existing methods require complex and laborious steps to form an enamel-like structure. Here we present a very simple and effective technique for forming artificial enamel in near-physiological solution using a substrate composed of amorphous calcium phosphate (ACP) nanoparticles. Without any functionalized modification of the substrate surface, faint dissolution and successive phase transformation automatically induce formation of an intermediate layer of low-crystalline HAP nanoparticles, on which highly oriented HAP nanorods grow by geometrical selection. We also show that an enamel structure forms on a substrate of amorphous calcium carbonate when the surface nanoparticles react so as to form an intermediate layer similar to that in ACP. Our results demonstrate that there is a wide range of substrate choices for nanorod array formation. Contrary to current understanding, a stable surface designed in nanoscale is not essential for the growth of arranged guest crystals. Reactive amorphous nanoparticles and their transformation efficiently induce a nanorod array structure.

The present study is an investigation to demonstrate the effectiveness of in situ approach in the synthesis of hydroxyapatitegrafted titanium nanotube composite (HA-TNT). This method involves combining the process of HA solÀgel and rapid breakdown anodisation of titanium in a novel solution consisting of NaCl and N 3 PO 4 . This new synthesis approach produced a uniform dispersion of Anatase and Rutile phases of TiO 2 nanotubes with minimal agglomeration in the matrix of crystalline HA. The characterisation of homogenised HA-TNT composite was investigated via field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), transmission electron microscope (TEM) and X-ray diffraction (XRD). FESEM and TEM images indicated the nanostructure of composite with TiO 2 nanotube diameter of approximately 10 nm. XRD and EDS analyses confirmed the formation of HA crystalline with the Ca/P ratio of 1.58 and formation of Anatase and Rutile phase of TiO 2 nanotubes.
