“…Hydroxyapatite (HAp), Ca10(PO4)6(OH)2, is a calcium fosfat that is a bioactive ceramic material with a high biological activity [7][8][9]. Additionally, HAp is osteo-conductive, bioactive, and biocompatible, allowing it to bond with the bone and stimulate bone regeneration-all essential components of treating bone harm.…”

The aim of this review was to determine the synthesis of hydroxyapatite biomaterial from bone waste by sol-gel method. The sol gel method was chosen because it can operate at low temperatures, simple method, inexpensive. Waste materials were used in the study since it is currently uncommon to synthesize bone implant hydroxyapatite using waste resources. Additionally, using waste products to create hydroxyapatite is a great way to help Indonesia reduce its waste production. Moreover, this review revealed the biowaste which excellent potential as the source of hydroxyapatite. As well as in this review it was found that heating the sample at 1000°C is necessary to synthesize pure hydroxyapatite, and the resulting material has unique characteristics as shown by XRD and FTIR patterns.

“…To address this issue, a biocompatible ceramic composite can be fabricated by associating HAP with another ceramic material with higher ε′. This approach offers the possibility of tuning the ε′ of HAP to meet the specific requirements for various biomedical applications. , Over and above, if the bioceramic composite is piezoelectric, then it will most likely develop charges under mechanical stress. These charges can aid in the bone-forming process by drawing necessary calcium and phosphate ions from the blood plasma, thereby expediting osteoblastic formation …”

This study focuses on investigating the intriguing properties of Ca 10 (PO 4 ) 6 (OH) 2 (HAP)−K 0.5 Na 0.5 NbO 3 (KNN) bioceramic composites, seeking to elucidate the relationship between their structural, electrical, biological, and optical behavior. The article begins with a close inspection of the O 1s spectra of the specimens obtained from X-ray photoelectron spectroscopy (XPS). The spectra reveal the peak related to lattice oxygen, O vacancy and the surface adsorbed O. The formed O vacancy strongly influences the changes in lattice parameters as observed from the X-ray diffraction (XRD) patterns. The frequency variation of the dielectric response for the composites in the radio frequency (RF) regime has electrical polarization effective for biomedical applications. Nyquist plots along with equivalent RC circuits further confirm that those electrical responses are mainly contributed from the grain boundaries. Adsorption dynamics of protein on the ceramic surface are investigated using bovine serum albumin (BSA), which established the major role of electrostatic interaction. Surface charge and O vacancies are modeled to understand the adsorption of protein and a linear correlation is reported. The role of O vacancies in modulating adsorption dynamics adds a new dimension to this study. The conformational change of BSA has also been considered by constructing the secondary structure following the protein-ceramic interaction. Excitingly, the composites are also found to be fluorescent active, a courtesy of the defects and vacancies leading to electron−hole recombination in the forbidden region. These promising properties envision an exciting future for HAP-KNN composites, especially in the domain of bioimaging and bone-tissue engineering.
