Abstract
Background and objective: In recent years, two-dimensional nanomaterials are widely used in biomedical applications. Graphitic carbon nitride has been significant not only due to good biocompatibility but also because of its application in the bio-imaging, diagnosis, and treatment of cancer. The purpose of this study was to investigate the effect of graphitic carbon nitride on viability of Saos-2 cancer cell line.
Methods: Graphitic carbon nitride was synthesized by adding melamine to hydrochloride acid and its physicochemical properties and structure was evaluated using FTIR, XRD, and Raman spectroscopy. Synthesized graphitic carbon nitride (50, 100, 200, 400, and 800 μg/mL) was added on Saos-2 cells and fibroblasts in two periods of 48 and 72 hours. The survival rate of the cells was investigated by MTT.
Findings: The results of FT-IR and XRD tests showed the structure and bonds of the synthesized compound, its accuracy and purity, respectively. Raman spectroscopy results also showed the graphitic content of the synthesized product. After passing 48 hours of the exposure of the cells to synthesized graphitic carbon nitride, the level of cell survival in the group that received 800 µg/mL was decreased to nearly 80% compared to the control (untreated) group.
Conclusion: The synthesized compound in this study might be considered as an appropriate option in cancer related researches.

Abstract
Objective: Osteon has been introduced as a bone substitute material. It is biphasic calcium phosphate (BCP) that use in dentistry. The aim of the present study was to evaluate the effect of osteon on the proliferation, cell viability and differentiation of saos-2 cells in vitro. Also it was compared with cerasorb bone graft.
Materials and Methods: Two different bone grafts materials, osteon and cerasorb, were used to evaluate the effect on proliferation and differentiation rate of saos-2 cells. On day 15 the cell proliferation and cell viability was measured by MTT assay. For determination of differentiation, alkaline phosphatase and alizarin red test was used.
Results: Osteon and cerasorb groups showed significantly higher alkaline phosphatase activity and cell differentiation. Cell viability of both bone grafts was significantly lower than control group and cell proliferation was higher in osteon group. Osteon has more suitable biological property compare to cerasorb.
Conclusions: The results of the present study showed that osteon and cersorb bone grafts allow proliferation and differentiation of saos-2 cells in vitro.
