Glutamic acid (GLU) plays an important role in bone cell signaling, intracellular communication, and nucleation of calcium phosphates. The objective of this work was to synthesize beta –tricalcium phosphate / Glutamic acid (βTCP/Glu) composites by in-situ and ex-situ approaches. Glu concentration was varied during synthesis. XRD results showed both method of fabrication, and Glu concentration affected the crystallinity and particle size of the final product. Interaction between βTCP and Glu was characterized by FTIR analysis. Changes in dissociation temperature of Glu using differential scanning calorimetry (DSC) method showed the interaction mechanism varied in these samples. Samples were characterized using field emission electron scanning microscopy (FESEM) and particle size analyzer. Results showed that βTCP/Glu composites properties are highly dependent on fabrication method as well as precursor’s initial concentration. The poster will present synthesis and characterization of these βTCP/Glu particles which can be used in bone graft and related biomedical applications.
