Physicochemical Characterization of Biomineralized Structures of Sea Pen Pteroeides spinosum (Ellis & Solander, 1786) (Octocorallia: Pennatulidae)

In this study, biomineralized polyp leaf spicules and the endoskeletal axis of the coral Pteroeides spinosum were physicochemically characterized by FTIR, SEM, EDX, TGA, XRD, ICP-MS, and ICP-OES analyses. The mineralized inner axis and polyp leaf spicules of P. spinosum were also pulverized and incorporated into the polyacrylamide (PAAm) hydrogel structure. In vitro bioactivity of coral polyp leaf spicules was evaluated by using simulated body fluid. Characterization analyses identified the major crystalline phase of coral polyp leaves spicules and the inner axis as calcite. The coral's inner axis exhibits a notched and perforated surface morphology. Calcite sclerites obtained from polyp leaves exhibit a crystalline structure and smooth surface morphology. TGA results revealed the organic matter in the coral individual is higher than that of the polyp leaf spicules. It resulted the coral's inner axis was compatible with the PAAm hydrogel. Coral polyp leaf spicules did not form apatite on their surface in simulated body fluid. The calcite content of the coral P. spinosum can be evaluated as an inert additive to improve mechanical properties and thermal stability in hydrogels.
