Force Spectroscopy with the Atomic Force Microscope
Introduction and Review Atomic Force Microscope (AFM) Spectroscopy is an AFM based technique to measure, and sometimes control the polarity and strength of the interaction between the AFM tip and the sample. Although the tip-sample interaction may be studied in terms of the energy, the quantity that is measured first is always the tip-sample force, and thus the nomenclature: force spectroscopy....
متن کاملVisualization of cytoskeletal elements by the atomic force microscope.
We describe a novel application of atomic force microscopy (AFM) to directly visualize cytoskeletal fibers in human foreskin epithelial cells. The nonionic detergent Triton X-100 in a low concentration was used to remove the membrane, soluble proteins, and organelles from the cell. The remaining cytoskeleton can then be directly visualized in either liquid or air-dried ambient conditions. These...
متن کاملMolecular visualization of immunoglobulin switch region RNA/DNA complex by atomic force microscope.
Immunoglobulin heavy-chain (IgH) class switch recombination (CSR) is initiated by DNA breakage in the switch (S) region featuring tandem repetitive nucleotide sequences. Various studies have demonstrated that S-region transcription and splicing proceed to genomic recombination and are indispensable for CSR in vivo, although the precise molecular mechanism is largely unknown. Here, we show the n...
متن کاملSensitivity of an Atomic Force Microscope Cantilever with a Crack
The atomic force microscope (AFM) has become an essential tool for the measurement of surface characteristics of diverse materials on a microand nanoscale level [1]. The resolution of measurements for the AFM cantilever is related to its vibration sensitivity. Many researchers have much interest in studying the resonant frequency and sensitivity analysis of AFM cantilevers [2 4]. Cracks may be ...
متن کاملMeasuring Nanoscale Stress Intensity Factors with an Atomic Force Microscope
Atomic Force Microscope images of a crack intersecting the free surface of a glass specimen are taken at different stages of subcritical propagation. From the analysis of image pairs, it is shown that a novel Integrated Digital Image Correlation technique allows to measure stress intensity factors in a quantitative fashion. Image sizes as small as 200 nm can be exploited and the surface displac...
