“…It sounds a bit unusual that the disposed bony parts of turbot can be a useful resource for bioceramic production with very low carbon footprint. Besides, any production based on fish bone will be much safer, because it will not bear any prion diseases like the bovine bones do, especially with freeze drying method (high temperature calcination is safe) [3]. Natural HA is always the best resource for human bone tissue corrections for orthopedic, dental and cosmetic surgeries.…”

Nowadays hydroxyapatite is one of the most popular biomaterials, which is used in various medical and dental applications areas as graft material. Bovine bone is the biggest source for natural hydroxyapatite production, but its production can lead to very dangerous disease, like mad cow disease, without high degree calcination. Hydroxyapatite produced from marine sources is much safer and easier to produce than bovine hydroxyapatite. Here in this study natural hydroxyapatite and related phases were produced from a local source turbot (Psetta maxima). Beside the main bony internal structure, there are koshers (cycloid scale) on its skin. Koshers are bulky bumps, looking like flat, small and rounded structures. Internal bones and those bulky bumps were cleaned from flesh with chemicals and calcined at 850• C for 4 hours. After calcinations, especially those bulky bumps, were formed into mesoporous structures with very light bluish color. Those mesoporous structures can be used as natural mesoporous hydroxyapatite structures for bone grafting purposes. The internal bones have also formed hydroxyapatite. Scanning electron microscope and X-ray diffraction studies were performed. I this study it is found that the bones of turbot consist of hydroxyapatite and TCP related phases. The aim of this study is to produce natural hydroxyapatite structures from turbot scale with low carbon footprint, without harming the environment and without using complex chemicals.

“…Sol-gel glasses can be produced at low temperature conditions with good homogeneity. The sol-gel method offers potential benefits for obtaining the powdered materials with good control of composition, microstructure, and wider range of bioactivity (Ahmed et al 2012;Bellucci et al 2012;Goller et al 2004;Arcos and Vallet-Regíl 2010). Sol-gel process is a more convenient technique than melt quenching technique to improve HCA layer growth rate in simulated body fluid (SBF) solution based on dissolution property of synthesised glass-ceramics in SBF solution.…”

Barium soda lime phosphosilicate [(58SiO 2 -(32 -x)BaO-xCao-6Na 2 O-4P 2 O 5 (where x = 15, 20, 25 and 30 mol%)] samples were synthesised using conventional sol-gel method at 700°C sintering temperature. Thermal, structural properties were studied using thermo gravimetric analysis and differential thermal analysis, X-ray diffraction, scanning electron microscopy, fourier transform infrared and Raman spectroscopy. Using Raman spectra non-bridging oxygen concentrations were estimated. The hydroxy-carbonated apatite (HCA) layer formation on samples was analysed for 7 days using simulated body fluid (SBF) soaked samples. The growth of HCA layers self-assembled on the sample surface was discussed as a function of NBO/BO ratio. Results indicated that the number of Ca 2? ions released into SBF solution in dissolution process and weight loss of SB-treated samples vary with NBO/BO ratio. The changes in NBO/BO ratios were observed to be proportional to HCA forming ability of barium soda lime phosphosilicate glasses.

“…Natural HA types are produced from various natural sources (i.e. human bone-tooth, bovine bone, sheep bone, chicken bone) with calcination method [3][4][5][6][7][8][9]. Besides HA, there are other apatite-like materials which could be easily resorbed at orthopaedic and dental * corresponding author; e-mail: bozkurtdu@itu.edu.tr grafting procedures, like other calcium phosphates with resorable phases (α-tricalcium phosphate, β-tricalcium phosphate or whitlockite) [10][11][12][13][14].…”

Bioceramic Production from Sea Urchins

et al. 2012

Bioceramic nanopowders, currently one of the most demanding challenges for producing new biomaterials, have been tackled only when starting from chemical reagents. There are few studies aiming at producing hydroxyapatite nanopowders from naturally derived raw materials, such as nacre shells. Natural species of sea origin, such as corals and nacres, always attract special interest in biomaterials science and technology. Nacre shells are made up of pure aragonite crystallized in an organic matrix. The most common way to transform aragonite structures to hydroxyapatite is via hydrothermal transformation under very high pressure. However, such ways can be very dangerous if the equipment is worn. Ultrasonic and hotplate methods are apparently very safe. This work proposes a new approach for developing highly bioactive fine powders of Ca-phosphates (which can be used afterwards to build up hydroxyapatite-based bioceramic bone-scaffolds) from sea urchins via the above mentioned methods. The suspended raw powders were put on a hotplate (i.e. ultrasound). The temperature was set to 80• C for 15 min and then, equivalent (to the amount of CaCO 3 in the sea urchins) amount of H 3 PO 4 was added drop by drop into the solution. The reaction continued for 2 h. Then, to evaporate the liquid part, the mixture was put into an incubator at 100• C for 24 h and the resultant dried sediment was collected. X-ray diffraction analysis identified various calcium phosphate phases, predominantly monetite, and tricalcium phosphate as a secondary phase. The worldwide availability and the low cost of all kinds of nacre and sea urchin shells, along with their biological-natural origin are attractive features conferring to them a high potential for preparing calcium phosphate materials for uses in biomedicine. Heart urchin, used in this study, can be an ideal candidate for producing bioceramic particles.
