Erratum: ‘‘Calibration of atomic‐force microscope tips’’ [Rev. Sci. Instrum. 64, 1868 (1993)]
TLDR
In this article, the frequency response of the optical-detection electronics of an atomic-force microscope cantilever was corrected for a high frequency cut-off, which, in our case, was higher than the resonant frequency of the cantilevers.Abstract:
In our calibration of atomic-force microscope cantilevers, we neglected to correct for the frequency response of the optical-detection electronics. The response to cantilever vibrations will have a high-frequency cut-off, which, in our case, was higher than the resonant frequency of the cantilever. Our results were not affected, but for higher resonant frequencies, one should calibrate the detector response. We thank V. Croquette for raising this point.read more

Role of material microstructure in plate stiffness with relevance to microcantilever sensors
TL;DR: In this article, the effect of microstructure on microcantilever bending stiffness was examined using an isotropic Hooke's law constitutive relationship, compared to a model based upon a micropolar elasticity constitutive model.

Topography and Mechanical Properties of Single Molecules of Type I Collagen Using Atomic Force Microscopy
Laurent Bozec,Michael A. Horton +1 more
TL;DR: T trimeric type I tropocollagen molecules are studied by atomic force microscopy and force spectroscopy to establish the stretching pattern of the molecule, where both the mechanical response of the molecules and pull-off peak are convoluted in a single feature.

Thermomechanical noise of a free v-shaped cantilever for atomic-force microscopy.
TL;DR: The results indicate a systematic deviation of the spectral density of the thermomechanical noise of v-shaped cantilevers as compared to rectangular beam-shaped Canticlever, as well as the numerical constants, which are needed for the calibration using the thermal noise method.

Mechanical control of the sense of touch by β-spectrin
TL;DR: It is shown that spectrin is held under constitutive tension in living animals, which contributes to elevated pre-stress in touch receptor neurons, and genetic manipulations that decrease such spectrin-dependent tension also selectively impair touch sensation, suggesting that such pre-tension is essential for efficient responses to external mechanical stimuli.
