“…In this regard, some recent studies applied microwave treatment under reflux conditions using EDTA as the chelating agent for production of HA [106,107]. In all instances, either HA nano powder or nano strips were obtained with particle sizes of less than 100 nm with different morphologies (rod shape, flower like, elliptical, bowknot) depending on the treatment conditions (time, temperature and pressure).…”

Marine shell waste is a very rich source of several bioactive compounds and materials, such as calcium, chitin, pigments and proteins. Currently, this waste material is greatly underutilized and contributes to significant environmental problems due to off odour and concentration of minerals in landfill. The main objective of this review is to highlight the potential to value-add to and maximize the utilization of this waste stream. Therefore, this review provides up to date Downloaded by [University of California Santa Barbara] at 06:53 25 June 2016 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2information on various compounds available in marine shells that are generated as waste co-product from commercial processing operations and their potential uses. Methods are described for extraction of these compounds for use in food and pharmaceutical applications.

The aim of this paper is to present the current status on animal-origin hydroxyapatite (HA) coatings synthesized by Pulsed Laser Deposition (PLD) technique for medical implant applications. PLD as a thin film synthesis method, although limited in terms of surface covered area, still gathers interest among researchers due to its advantages such as stoichiometric transfer, thickness control, film adherence, and relatively simple experimental set-up. While animal-origin HA synthesized by bacteria or extracted from animal bones, eggshells, and clams was tested in the form of thin films or scaffolds as a bioactive agent before, the reported results on PLD coatings from HA materials extracted from natural sources were not gathered and compared until the present study. Since natural apatite contains trace elements and new functional groups, such as CO32− and HPO42− in its complex molecules, physical-chemical results on the transfer of animal-origin HA by PLD are extremely interesting due to the stoichiometric transfer possibilities of this technique. The points of interest of this paper are the origin of HA from various sustainable resources, the extraction methods employed, the supplemental functional groups, and ions present in animal-origin HA targets and coatings as compared to synthetic HA, the coatings’ morphology function of the type of HA, and the structure and crystalline status after deposition (where properties were superior to synthetic HA), and the influence of various dopants on these properties. The most interesting studies published in the last decade in scientific literature were compared and morphological, elemental, structural, and mechanical data were compiled and interpreted. The biological response of different types of animal-origin apatites on a variety of cell types was qualitatively assessed by comparing MTS assay data of various studies, where the testing conditions were possible. Antibacterial and antifungal activity of some doped animal-origin HA coatings was also discussed.

“…In view of the variety of roles played by bioceramics in different tissues, researches have focused on developing novel biomaterials to mimic the bone structure. Bone is a composite structure composed of HA crystalls that dipersed througout an biocompatible polymeric matrics [2]. In the proposed study, in order to mimic bone structure, beside a bioceramic (HA) biocompatible polycaprolactone (PCL) and polyvinylpyrrolidon (PVP) were chosen to prepare electrospun composites of PCL-PVP-HA, for tissue engineering purposes.…”

In the present study, hydroxyapatite (HA) and tricalcium phosphate (TCP) bioceramics were prepared via a practical, ultrasonic conversion method from Donax trunculus seashells. These seashells are one of the most common bivalve molluscs of the Mediterranean Sea and can be used as a natural, stable raw material for bioceramic production. Ultrasonication, a powerful method for nano-sized ceramic production, was chosen to synthesize different ceramic phases easily. Raw shells are consisted of calcite and aragonite structures. To synthesize HA and TCP bioceramic materials, first the calcium oxide content of the shells were identified via Differential Thermal Analysis (DTA) and then a calculated amount of phosphoric acid was added drop by drop to obtain the exact stoichiometry. After synthesis, the resultant bioceramics were sintered at 800-850 • C for HA and 400-450 • C for TCP phases. For bioceramic phases X-ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FTIR), Field Emission Gun Scanning Electron Microscope (FEGSEM) studies were perform. On the other hand, electrospinning method was used to prepare nanobiocomposites from biocompatible polymeric material as the matrix and the obtained natural bioceramics as reinforcer of the composite system. Three different compositions were used and optimum electrospinning conditions were adjusted to prepare these electrospun structures. Biocomposites were evaluated in terms of structure, mechanic, morphology and biology. The effect of bioceramic content was also discussed. It is revealed that the obtained electrospun nanobiocomposites are good candidates for various tissue engineering purposes due to their enhanced biological and mechanical properties.
