Molecular Dynamics Study of Stability and Diffusion of Graphene-Based Drug Delivery Systems

Figure 5

Average in-plane diffusion coefficients of one drug molecule loaded on the graphene sheets of 10–50 Å in (a) single-side and (b) double-side modes. The dashed lines represent the average in-plane diffusion coefficients of one drug molecule loaded on periodic graphene in (a) single-side and (b) double-side modes. The diffusion coefficients of four types of drug molecules CE6, DOX, MTX, and SN38 are shown in the figures, respectively.
