How AFM works (2596 words)
AFM (figure 1) operates by measuring attractive or repulsive forces between a tip and the sample (Binnig et al., 1986).
The feedback loop (figure 6) consists of the tube scanner that controls the height of the entire sample; the cantilever and optical lever, which measures the local height of the sample; and a feedback circuit that attempts to keep the cantilever deflection constant by adjusting the voltage applied to the scanner.
The ability of AFM to image at atomic resolution, combined with its ability to image a wide variety of samples under a wide variety of conditions, has created a great deal of interest in applying it to the study of biological structures.
What is AFM? (415 words)
