✦ Synopsis
Atomic force microscopy (AFM) is the only available experimental technique to image individual biological molecules in liquid environment with subnanometer resolution. Recently, a frequency-modulation (FM) technique has been used to enhance the resolution of AFM in liquid, resulting in images showing atomic resolution and atomic-scale defects ("true atomic resolution''). FM-AFM also allows to better control the imaging conditions and the applied forces than conventional modes of operation of AFM in liquid.
