“…In the 300 650 cm À1 region, the Raman spectrum exhibits bands especially at 587 cm À1 assignable to the ʋ 4 PO 4 bending mode. In addition, Raman bands are detected at 380 and 411 cm À1 and are assigned to the ʋ 2 PO 4 bending [48]. Similar results were observed for pure DCPD by Petrov et al [46].…”

Ion substitution Human stem cells Bone biomaterial Calcium phosphate Dicalcium phosphate dihydrate, DCPD (CaHP0 4 •2H 2 O), brushite, is an important calcium phosphate compound encountered in mineralized tissues and used in medicine, especially in bone cernent for mulations. However, the use of DCPD as direct implantable biomaterial has not received dedicated attention. In addition, the possibility to dope DCPD with biologically active ions to modulate its per formances was not systematically explored. We have investigated in depth the doping of DCPD with Mg 2+ , sr2 + , Zn 2+ , Cu 2+ , and Ag + ions. Clear modifications in terms of chemical composition, particl e size, pore distribution, crystal morphology, and affinity for water were pointed out. Then, the samples were cultured with human adipose derived stem cells to explore cytotoxicity and proliferation. Various be haviors were noticed dependent on the incorporated metal ions. Such DCPD compounds associated with bioactive metal ions, and particularly Ag + and Zn 2+ , appear promising as a new family of reactive ma terials for use, as such or in combination, in bone related applications.

“…Additionally, a shoulder at 1725 cm− 1 was observed, which is related to the flexural stress of the water molecule, and the signals obtained at 3548, 3484, 3278, and 3166 cm− 1 are related to the extension of the water molecule in the apatite. Finally, a band at 2944 cm− 1 was also observed, directly related to the stretching of PO-H that occurs in HPO [1,41,42]. In the case of the nDCPD spectra with the different metal ions, it was observed that several peaks decrease in intensity or disappear as a result of the presence of Ni, Co, and Cu; these signals are related to the PO 3 − 4 and OH groups, with which it can be inferred that the groups present on the surface of this apatite participate in the adsorption of metals directly.…”

Recently the interest in the remediation of liquid effluents from industries such as paint manufacturing, leather tanning, etc. has increased, because the quality of the water used in these processes is highly compromised and is generally discarded without any process of purification, causing an inadequate use of water and contributing to the hydric stress of the planet. Therefore, it is necessary to find alternatives for the remediation of water used in industrial processes; one of the methods that has been widely accepted given its high efficiency, low cost, and versatility compared to others is the bioadsorption using materials derived from various processes used for the elimination of metals such as Cr, Co, Cu, Ni, etc. from liquid effluents. Among the materials used for this purpose are rice husk, orange, and wheat as well as apatite (hydroxyapatite and brushite), derived from animal bones, which have shown good capacity (>90%) to adsorb metals from aqueous solutions. Through the characterization by DRX, FTIR, and SEM, of the brushite and studies in equilibrium and kinetics of adsorption, it has been demonstrated that this material has a good capacity to remove metals present in water.

BackgroundBone regeneration involves various complex biological processes. Many experiments have been performed using biomaterials in vivo and in vitro to promote and understand bone regeneration. Among the many biomaterials, calcium phosphates which exist in the natural bone have been conducted a number of studies because of its bone regenerative property. It can be directly contributed to bone regeneration process or assist in the use of other biomaterials. Therefore, it is widely used in many applications and has been continuously studied.MainbodyCalcium phosphate has been widely used in bone regeneration applications because it shows osteoconductive and in some cases osteoinductive features. The release of calcium and phosphorus ions regulates the activation of osteoblasts and osteoclasts to facilitate bone regeneration. The control of surface properties and porosity of calcium phosphate affects cell/protein adhesion and growth and regulates bone mineral formation. Properties affecting bioactivity vary depending on the types of calcium phosphates such as HAP, TCP and can be utilized in various applications because of differences in ion release, solubility, stability, and mechanical strength. In order to make use of these properties, different calcium phosphates have been used together or mixed with other materials to complement their disadvantages and to highlight their advantages. Calcium phosphate has been utilized to improve bone regeneration in ways such as increasing osteoconductivity for bone ingrowth, enhancing osteoinductivity for bone mineralization with ion release control, and encapsulating drugs or growth factors.ConclusionCalcium phosphate has been used for bone regeneration in various forms such as coating, cement and scaffold based on its unique bioactive properties and bone regeneration effectiveness. Additionally, several studies have been actively carried out to improve the efficacy of calcium phosphate in combination with various healing agents. By summarizing the properties of calcium phosphate and its research direction, we hope that calcium phosphate can contribute to the clinical treatment approach for bone defect and disease.
