Characterization of Silk Fibroin Modified Surface: A Proteomic View of Cellular Response Proteins Induced by Biomaterials
Figure 2
AFM images of the QCM chip. (a) Blank, 50 × 50 μm, (b) CNTs, 50 × 50 μm. AFM measurements could also be used for measuring the surface roughness of the QCM chip. The mean surface roughness was 1.0 and 2.3 nm for blank and CNTs surfaces, respectively.
