Atomic Force Microscopy in the Study of Macromolecular Crystal Growth

▪ Abstract Atomic force microscopy (AFM) has been used to study protein, nucleic acid, and virus crystals in situ, in their mother liquors, as they grow. From sequential AFM images taken at brief intervals over many hours, or even days, the mechanisms and kinetics of the growth process can be defined. The appearance of both two- and three-dimensional nuclei on crystal surfaces have been visualized, defect structures of crystals were clearly...
