Atomic force microscopy (AFM) force-distance curves have become a fundamental tool in several fields of research, such as surface science, materials engineering, biochemistry and biology. Furthermore, they have great importance for the study of surface interactions from a theoretical point of view. ...
Compared to other instruments, the AFM has in this case two major advantages. First of all, elastic moduli of samples can be measured with high resolution from some GPa down to some MPa, which is the range of the elastic moduli of common polymers. Second, force–distance curves can be ...
Since 1989, the atomic force microscope (AFM) has emerged as a useful tool in studying surface interactions by means of force-distance curves, and a great deal of work has been carried out on both its theoretical and experimental issues. AFM is able to acquire force-distance curves from ever...

The red circle represents the value of 𝑥∗x* calculated at the most probable folding force, by using the experimental folding kinetic rates. (c) Fragility of barnase versus force. From the force–distance curves, we extract the rupture force distributions 𝜌→(𝑓)ρ→(f) and 𝜌←(...
Fast Force Mappingon Cypher AFMs measures force-distance curves at high speed (up to 1000 Hz) while capturing every curve in the image. Both real-time and offline analysis models can be applied to calculate modulus, adhesion, and other properties. ...
Atomic force microscopy (AFM) has been used in a wide variety of biological studies, from the topography imaging to the interactions of both sub-cell molecular (i.e., DNA and protein) and cell membranes. Particularly, the force-curve measurement using AFM has become a powerful tool to study...
Force-distance measurements enable researchers to study attractive and repulsive forces on a probe as it approaches and retracts from a sample surface.
