In cellular biology, traction force microscopy (TFM) is an experimental method for determining the tractions on the surface of a cell by obtaining measurements of the surrounding displacement field within an in vitro extracellular matrix (ECM).
The most prevalent and accurate modern method for measuring the traction forces that cells exert on the substrate relies on traction force microscopy (TFM). The principle behind this method is to measure deformation in the substrate by calculating 2-dimensional displacement of fluorescent beads that are embedded in the matrix.
Scheme of the colloidal probe technique for direct force measurements in the sphere-plane and sphere-sphere geometries. The colloidal probe technique is commonly used to measure interaction forces acting between colloidal particles and/or planar surfaces in air or in solution. This technique relies on the use of an atomic force microscope (AFM).
This traction can be visualized with traction force microscopy. A common metaphor to explain actin retrograde flow is a large number of people being washed downriver, and as they do so, some of them hang on to rocks and branches along the bank to stop their downriver motion.
On the left is the control unit with lock-in amplifier and backing potential controller. On the right is the x, y, z scanning axis with vibrator, electrometer and probe mounted. Kelvin probe force microscopy (KPFM), also known as surface potential microscopy, is a noncontact variant of atomic force microscopy (AFM).
Electrochemical AFM (EC-AFM) is a particular type of Scanning probe microscopy (SPM), which combines the classical Atomic force microscopy (AFM) together with electrochemical measurements. EC-AFM allows to perform in-situ AFM measurements in an electrochemical cell , in order to investigate the actual changes in the electrode surface morphology ...
The variety of techniques can be divided into two categories: force application techniques and force sensing techniques. [1] In case of walled cells, such as plant or fungal cells, due to existence of a stiff, anisotropic and curved cell wall encapsulating the cells, special considerations and tailored approaches may be required compared to the ...
