Effect of the Tip Size on AFM Cantilever Based Force Sensor

Figure 3

Cell adhesion force measurement results. (a) SEM images of the cell and end effector with small tip size (1.0 μm). (b) SEM images of the cell and end effector with large tip size (4.0 μm). (c) Comparison of the cell adhesion force by the end effector based on the beam deflection. The scale bar is 5 μm. The dashing lines indicate the deflection of the cantilever beam and the triangles indicate the position of the cell.
