Study of Amyloid Fibers Using Atomic Force Microscopy.

Atomic force microscopy (AFM) provides high-resolution images of the topography of amyloid fibers adsorbed on surfaces. This information is very useful to study their molecular assembly under various conditions. This chapter describes the basic protocols required to deposit fibers on flat surfaces and discusses some of the practical issues required to operate a good commercial microscope setup to obtain appropriate high-resolution AFM topographic images of amyloid fibers.
