“…Somewhat weaker bands at 382, 415 and 525 cm −1 are due to O-P-O bending vibrations of the HPO 4 2− ion [45,50,58]. A band at 584 cm −1 is from P-O-and O-P-O stretching and bending vibrations of the PO 4 3− ion [45,51,[56][57][58]. These bands are characteristic for DCPD and thus confirm the XRD data shown above.…”

Abstract:The effect of cellulose-based polyelectrolytes on biomimetic calcium phosphate mineralization is described. Three cellulose derivatives, a polyanion, a polycation, and a polyzwitterion were used as additives. Scanning electron microscopy, X-ray diffraction, IR and Raman spectroscopy show that, depending on the composition of the starting solution, hydroxyapatite or brushite precipitates form. Infrared and Raman spectroscopy also show that significant amounts of nitrate ions are incorporated in the precipitates. Energy dispersive X-ray spectroscopy shows that the Ca/P ratio varies throughout the samples and resembles that of other bioinspired calcium phosphate hybrid materials. Elemental analysis shows that the carbon (i.e., polymer) contents reach 10% in some samples, clearly illustrating the formation of a true hybrid material. Overall, the data indicate that a higher polymer concentration in the reaction mixture favors the formation of polymer-enriched materials, while lower polymer concentrations or high precursor concentrations favor the formation of products that are closely related to the control samples precipitated in the absence of polymer. The results thus highlight the potential of (water-soluble) cellulose derivatives for the synthesis and design of bioinspired and bio-based hybrid materials.

“…Spectra obtained from samples precipitated from 100 mM solution show strong bands at 991 and 887 cm −1 ; these bands can be assigned to P-O stretching vibrations of the phosphate ion [45,50,51,[55][56][57][58]. Somewhat weaker bands at 382, 415 and 525 cm −1 are due to O-P-O bending vibrations of the HPO 4 2− ion [45,50,58].…”

“…However, the type of reaction responsible for setting and hardening these novel calcium carbonate-based bone cements differs from the well-studied and -developed CaP-based cements in several aspects. CaP biomedical cements can be classified into two categories: apatite and brushite cements that respectively lead to hydroxyapatite and brushite (Dicalcium Phosphate Dihydrate: DCPD) which is converted into apatite in vivo [8,64]. Two types of setting reactions can be distinguished for CaP cements: acid-base reaction and/or fast hydrolysis of a metastable CaP phase into apatite associated with respectively more or less pH variation of the paste during setting.…”

Preparation, physical–chemical characterisation and cytocompatibility of calcium carbonate cements

et al. 2006

The feasibility of calcium carbonate cements involving the recrystallisation of metastable calcium carbonate varieties has been demonstrated. Calcium carbonate cement compositions presented in this paper can be prepared straightforwardly by simply mixing water (liquid phase) with two calcium carbonate phases (solid phase) which can be easily obtained by precipitation. An original cement composition was obtained by mixing amorphous calcium carbonate and vaterite with an aqueous medium. The cement set and hardened within 2 hours at 37°C in an atmosphere saturated with water and the final composition of the cement consisted mostly of aragonite. The hardened cement was microporous and showed poor mechanical properties. Cytotoxicity tests revealed excellent cytocompatibility of calcium carbonate cement compositions. Calcium carbonates with a higher solubility than the marketed calcium phosphate cements might be of interest to increase biomedical cement resorption rates and to favour its replacement by bone tissue.
