Figure 6.13 AFM images of a Cyclopore membrane in electrolyte solutions (a-c) at various forces in 10 M NaCI solution (d-f) at approximately constant force at various ionic strengths. All data at pH 6.5. IF = imaging force.

Figure 6.19 Imaging a 1.0 m Cyclopore membrane with a 0.75 pm colloid probe in 0.1 M NaCI, pH 8 (left) in 0.0001 M NaCI, pH 8 (right). Normalized imaging force 4.6mN/m.

The figure shows how a 0.75 pm silica colloid probe sees the pores in a 1.0 pm Cyclopore membrane in solutions of two ionic strengths when imaged in each...
