ABSTRACT

Since the invention of atomic force microscopy (AFM) in 1986

[1], a variety of biological samples have been visualized using this

technique. AFM is now recognized as a versatile and powerful

analytical tool that can be used in many areas of biology. In this

chapter, we briefly overview how AFM works in imaging and

which factors affect successful imaging of biological samples, which

include the substrate, the cantilever, the setup, and image processing

(Fig. 2.1). Experimental protocols for specimen preparation of

biological samples, including DNA, protein, and cultured cells, are

also provided.
