Quantitative Nanotribology by AFM: A Novel Universal Calibration Platform [PDF]

open access: yes, 2006
The quantitative determination of friction forces by atomic force microscopy (AFM) in nanotribology requires the conversion of the output voltage signal of the sector area-sensitive photodiode to force using (a) the torsional spring constant of the ...

Role of Interfacial Water and Applied Potential on Friction at Au(111) Surfaces

open access: yesFrontiers in Mechanical Engineering, 2019
The tribological properties between an AFM tip and a Au(111) surface in an aqueous environment is influenced by an applied electrical potential. Using lateral force microscopy, we measure the resulting friction force, while simultaneously applying a pre ...

Nanotribology Results Show that DNA Forms a Mechanically Resistant 2D Network in Metaphase Chromatin Plates

open access: yes, 2010
In a previous study, we found that metaphase chromosomes are formed by thin plates, and here we have applied atomic force microscopy (AFM) and friction force measurements at the nanoscale (nanotribology) to analyze the properties of these planar ...
