Structural characteristics of surface-functionalized nitrogen-doped diamond-like carbon films and effective adjustment to cell attachment |
Cell morphologies on differently functionalized DLC:N films: (a) DLC:N, (b) DLC:N-DA, (c) DLC:N-APBA, and (d) DLC:N-ATP after 3-day culture. Cell nuclei are stained with DAPI in blue. Scale Bar is 50 μm. |
