Chaos in Atomic Force Microscopy
Physical Review Letters, 2006 Chaotic oscillations of microcantilever tips in dynamic atomic force microscopy (AFM) are reported and characterized. Systematic experiments performed using a variety of microcantilevers under a wide range of operating conditions indicate that softer AFM microcantilevers bifurcate from periodic to chaotic oscillations near the transition from the ...

Time-varying tip-sample force measurements confirm steady-state dynamics in tapping-mode atomic force microscopy [PDF]
Phys.Rev.B77:115405,2008, 2007 Direct time-varying tip-sample force measurements by torsional harmonic cantilevers facilitate detailed investigations of the cantilever dynamics in tapping-mode atomic force microscopy. Here we report experimental evidence that the mathematical relationships describing the steady state dynamics are quantitatively satisfied by the independent ...

Deep atomic force microscopy [PDF]
Review of Scientific Instruments, 2013 The Atomic Force Microscope (AFM) possesses several desirable imaging features including the ability to produce height profiles as well as two-dimensional images, in fluid or air, at high resolution. AFM has been used to study a vast selection of samples on the scale of angstroms to micrometers. However, current AFMs cannot access samples with vertical

Combined Traction Force–Atomic Force Microscopy Measurements of Neuronal Cells
Biomimetics, 2022 In the course of the development of the nervous system, neuronal cells extend (grow) axons, which navigate over distances of the order of many cell diameters to reach target dendrites from other neurons and establish neuronal circuits.
