Massively parallel cantilever-free atomic force microscopy

open access: yesNature Communications, 2021
Atomic force microscopy (AFM) provides high resolution, but is limited to small areas. Here, the authors introduce a massively parallel AFM approach with >1000 probes in a cantilever-free probe architecture, and present an optical method for detecting ...

Atomic resolution with high-eigenmode tapping mode atomic force microscopy

open access: yesPhysical Review Research, 2022
Atomic surface structure imaging is instrumental for the understanding of surface-related phenomena. Here, we show that conventional tapping mode atomic force microscopy with high cantilever eigenmodes and subnanometer amplitudes allow routine atomic ...

Electron scattering in atomic force microscopy experiments [PDF]

open access: yes, 2005
It has been shown that electron transitions, as measured in a scanning tunnelling microscope (STM), are related to chemical interactions in a tunnelling barrier.

Quantitative atomic force microscopy

open access: yesJournal of Physics: Condensed Matter, 2017
A variety of atomic force microscopy (AFM) modes is employed in the field of surface science. The most prominent AFM modes include the amplitude modulation (AM) and the frequency modulation (FM) mode. Over the years, different ways for analyzing data acquired with different AFM modes have been developed, where each analysis is usually based on mode ...

Potential contributions of noncontact atomic force microscopy for the future Casimir force measurements [PDF]

open access: yes, 2010
Surface electric noise, i.e., the non-uniform distribution of charges and potentials on a surface, poses a great experimental challenge in modern precision force measurements.

Atomic force microscopy of anisotropic silicone magnetoactive composites [PDF]

open access: yesE3S Web of Conferences, 2023
New anisotropic magnetically active elastomers using carbonyl iron micrometer size ferromagnetic fillers in the silicone matrix were synthesized. Samples with orientation of the outer magnetic field strength vector applied in perpendicular or in parallel

Force Sensing on Cells and Tissues by Atomic Force Microscopy

open access: yesSensors, 2022
Biosensors are aimed at detecting tiny physical and chemical stimuli in biological systems. Physical forces are ubiquitous, being implied in all cellular processes, including cell adhesion, migration, and differentiation.

Gamble mode: Resonance contact mode in atomic force microscopy [PDF]

open access: yes, 1996
Active noise reduction has been accomplished in atomic force microscopy by applying a high frequency, low amplitude vibration to the cantilever while it is in contact with a surface.
