Elastic Membrane That Undergoes Mechanical Deformation Enhances Osteoblast Cellular Attachment and Proliferation

Figure 5

AFM images of 30 min UVO-activated Si membrane surfaces precoated with 2.5 𝜇g/mL FN. The surface roughness of (RMS) 3.7 nm was obtained. Plane view of the figure (left) shows clusters of FN molecules on the activated Si membrane; while the elevated view shows very rough ridges of clustered FN molecules adhering to the Si surfaces.
