Biological Effects of Plasma-Based Graphene Oxide Deposition on Titanium

Figure 4

MTT assay showing the biocompatibility of the various surface conditions with the result on a cell culture plate for control. After the plasma treatment with the indicated time, the L-929 mouse fibroblasts cells incubated on the surface for 3 days and MTT assay was performed. The argon plasma treatment enhanced the cell viability on the Ti surface. The biocompatibility of titanium treated for 60-second plasma treatment showed same as that of the cell culture plate.
