Improved in situ spring constant calibration for colloidal probe atomic force microscopy.
In colloidal probe atomic force microscopy (AFM) surface forces cannot be measured without an accurate determination of the cantilever spring constant. The effective spring constant k depends upon the cantilever geometry and therefore should be measured in situ; additionally, k may be coupled to other measurement parameters. For example, colloidal probe AFM is frequently used to measure the sli...
متن کاملBFPTool: a software tool for analysis of Biomembrane Force Probe experiments
BACKGROUND The Biomembrane Force Probe is an approachable experimental technique commonly used for single-molecule force spectroscopy and experiments on biological interfaces. The technique operates in the range of forces from 0.1 pN to 1000 pN. Experiments are typically repeated many times, conditions are often not optimal, the captured video can be unstable and lose focus; this makes efficien...
متن کاملAlternative spring force law for bead-spring chain models of the worm-like chain
e have developed a new spring force law which can be used in bead-spring chain models of the orm-like chain. The bead-spring chain has no bending potentials between the springs, and so iffers from the current models only in the functional form of the force law. This new model can ccurately represent a chain that contains many persistence lengths even if each spring represents nly a few persiste...
متن کاملA spring force formulation for elastically deformable models
<:ontinuous deformable models are generally represented using a grid of control points. The elastic properties are then modeled using the interactions between these points. The formulations based on elasticity theory express these interactions using stiffness matrices. These matrices store the elastic properties of the models and they should be evolved in time according to changing elastic prop...
متن کاملSpring constant calibration of atomic force microscope cantilevers of arbitrary shape.
The spring constant of an atomic force microscope cantilever is often needed for quantitative measurements. The calibration method of Sader et al. [Rev. Sci. Instrum. 70, 3967 (1999)] for a rectangular cantilever requires measurement of the resonant frequency and quality factor in fluid (typically air), and knowledge of its plan view dimensions. This intrinsically uses the hydrodynamic function...
