Asylum Research Webinar: Ultra-High Resolution AFM Imaging

 

Description

Miniaturization of cantilevers for atomic force microscopy has increased their resonant frequencies and decreased their thermal noise, allowing faster, lower noise measurements. When used in the extremely low-noise Cypher AFM, these levers have enabled significant improvements in imaging resolution in air and especially in liquids. On crystals, individual atomic point defects can now be routinely resolved and this higher resolution also extends to biological samples. Examples shown include the movement of individual point defects in bacteriorhodopsin, atomic point defects in calcite, and resolution of the double-helix structure of DNA in solution.
