Probing single biomolecules with atomic force microscopy
Abstract
During the last years, atomic force microscopy (AFM) has developed from a microscopy tool for solid-state surface science toward a method employed in many scientific disciplines, such as biology, for investigating individual molecules on a nanometer scale. This article describes the current status of the imaging possibilities of AFM on RNA, IgG, and gold-labeled cell adhesion proteoglycans, as well as of measurements of intermolecular binding forces between biomolecules in order to investigate their molecular structure, function, and elasticity.
