Microbial adhesion and ultrastructure from the single-molecule to the single-cell levels by Atomic Force Microscopy

The Cell Surface, 2019
In the last decades, atomic force microscopy (AFM) has evolved towards an accurate and lasting tool to study the surface of living cells in physiological conditions.

Comparison of photothermal and piezoacoustic excitation methods for frequency and phase modulation atomic force microscopy in liquid environments

AIP Advances, 2011
In attempting to perform frequency modulation atomic force microscopy (FM-AFM) in liquids, a non-flat phase transfer function in the self-excitation system prevents proper tracking of the cantilever natural frequency.

Determination of electrical parameters of individual multiwalled carbon nanotube using scanning probe microscopy techniques [PDF]

Омский научный вестник, 2018
Based on the combination of conductive atomic force microscopy (C-AFM) and electrostatic force microscopy (EFM), the electrical parameters of undoped, nitrogen- and boron-doped individual multiwalled carbon nanotubes (CNTs) have been determined.

Dissipation signals due to lateral tip oscillations in FM-AFM

Beilstein Journal of Nanotechnology, 2014
We study the coupling of lateral and normal tip oscillations and its effect on the imaging process of frequency-modulated dynamic atomic force microscopy. The coupling is induced by the interaction between tip and surface.

Topography and mechanical properties of single molecules of type I collagen using atomic force microscopy [PDF]

, 2005
Although the mechanical behavior of tendon and bone has been studied for decades, there is still relatively little understanding of the molecular basis for their specific properties.
