Abstract:
Atomic force microscopy (AFM) has become a well-established technique for imaging single biomacromolecules under physiological conditions. The exceptionally high spatial resolution and signal-to-noise ratio of the AFM enables the substructure of individual molecules to be observed. In contrast to other methods, specimens prepared for AFM remain in a plastic state, which enables direct observation of the dynamic molecular response, creating unique opportunities for studying the structure-function relationships of proteins and their functionally relevant assemblies. This review presents recent advances in methods and applications of AFM to imaging biological samples. It is clear that AFM will become an increasingly important tool for probing both the structural and kinetic properties of biological macromolecules.
