“…The band at 882 cm -1 corresponds to the P-O(H) stretching vibrations of the acidic phosphate group (HPO4). The broad peak at 1300 to 1450 cm -1 is due to the P-O-H in-plane bending, the broad band at approximately 1633 cm -1 is associated with the H-O-H bending and the rotation of the residual free water, 1125 cm -1 band was assigned to P-O stretching [61].…”

This work analyses the properties of calcium phosphate coatings obtained by pulsed laser deposition on the surface of the ferroelectric polymer material. Atomic force and scanning electron microscopy studies demonstrate that, regardless of the type of sputtering target, the calcium phosphate coatings have a multiscale rough surface that is potentially capable of promoting the attachment and proliferation of osteoblasts. This developed surface of the coatings is due to its formation mainly from a liquid phase. The chemical and crystalline 2 composition of the coatings depends on the type of sputtering target used. It was shown that, regardless of the type of sputtering target, the crystalline structure of the ferroelectric polymer material does not change. Cell viability and adhesion studies of mesenchymal stromal cells on the coatings were conducted using flow cytometry and fluorescent microscopy. These studies indicated that the produced coatings are non-toxic.

“…The liberation band at 2,800 cm −1 for the O-H stretching vibration band of HPO 4 −2 was obtained from FTIR spectra. The 0.5% GO/CPC composite exhibits clear absorption bands resulting from the symmetric stretching of P-O-P at 726 cm−1 24. This difference may be attributed to the presence of graphene oxide or the presence of hydroxyapatite in different stoichiometric form.…”

Background: Brushite (dicalcium phosphate dihydrate, DCPD) cement as a promising bioactive material for bone tissue engineering is widely used to treat defects. However, relatively poor mechanical properties of brushite cement limit its application in loadbearing conditions. The aim of this study is to investigate the effect of graphene oxide (GO) addition to the physical-mechanical-biological properties of brushite cement. Methods: The brushite types of cement were prepared by mixing β-tricalcium phosphate [β-TCP, Ca3 (PO4)2] and monocalcium phosphate monohydrate [MCPM, Ca(H2PO4)2. H2O]. GO was introduced at 0, 0.5, 2, and 5 wt.% with the liquid. MG63 cells were cultured on the GO/CPC surfaces to observe various cellular activities and hydroxyapatite (HA) mineralization. Results: Based on our results, GO/CPC composites exhibit improvement in compressive strength compared to pure CPC. New Ca-deficient apatite layer was deposited on the composite surface after immersing immersion in SBF for 7 and 14 days. Field emission scanning electron microscope (FESEM) images indicated that pure and GO incorporated brushite cement facilitates cell adhesion. CPC/GO was slightly toxic to cells such that high concentrations of GO decreased the cell viability. Besides, alkaline phosphatase (ALP) activity of cells was improved compared with the pure CPC. Conclusion: Our results highlight the role of graphene oxide that may have great potential in enabling the utility of graphene-based materials in various biomedical applications.
