Atomic force microscopy ( AFM ) or scanning force microscopy ( SFM ) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. Overview Atomic for...

In microscopy, conductive atomic force microscopy ( C-AFM ) or current sensing atomic force microscopy ( CS-AFM ) is a mode in atomic force microscopy (AFM) that simultaneously measures the topography of a material and the electric current flow at the contact point of the tip with the surf...
Non-contact atomic force microscopy ( nc-AFM ), also known as dynamic force microscopy ( DFM ), is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In nc-AFM a sharp probe is moved close (order of Angstroms) to the surface under study, the probe is th...

The Atomic Force Microscopy Nanosurf FlexAFM System of the Centro de Química da Madeira (CQM, University of Madeira), is the first AFM equipment in Autonomous Region of Madeira, Portugal. This equipment is intended for research and has as its main priority the activities/research within the scope of the ECOFIBRAS Project (MAC / 4.6D / 040) for the topographic characterization of fibers of invasive species of Macaronesia, and as part of the research activities of CQM, the study of polymer fiber...
Bimodal Atomic Force Microscopy (bimodal AFM) is an advanced atomic force microscopy technique characterized by generating high-spatial resolution maps of material properties. Topography, deformation, elastic modulus, viscosity coefficient or magnetic field maps might be generated. Bimodal...
What is Atomic Force Microscopy? ; F = -kz ; A stiff cantilever is oscillated closer to the sample than in noncontact mode. Part of the oscillation extends into the repulsive regime, so the tip intermittently touches or taps the surface. Very stiff cantilevers are typically used, as tips can get stuck in the water contamination layer. Force Modulation ; Electrical Modes for AFM ; This mode can be done as a lift technique (dual pass) or as a single-pass method. The single-pass method, referred to...
