Representative top-down scanning electron microscopy (SEM) micrographs of adherent cells on different comb structures and blanket tantalum (Ta) film. Results show that adherent cells are aligned to the line axes on structures with line widths in the range of 0.18 to 10 μm. In contrast, cells on the 50 μm and 100 μm structures do not align well with the line axes—they are similar to cells randomly distributed on blanket Ta films. All cells were incubated on these specimens for 24 h.
