Mechanical properties of ultrathin membranes consisting of one layer, two overlapped
layers, and three overlapped layers of graphene oxide platelets were investigated by atomic …

Atomic force microscopy is an amazing technique that allies a versatile methodology (that
allows measurement of samples in liquid, vacuum or air) to imaging with unprecedented …

Atomic force microscopy (AFM) is a useful tool, not only for imaging but also for
quantification of normal and lateral forces exerted on the AFM tip while interacting with the …

for a rectangular cantilever requires measurement of the resonant frequency and quality
factor in fluid (typically air), and knowledge of its plan view dimensions. This intrinsically …

Recent studies indicate that the biophysical properties of the cellular microenvironment
strongly influence a variety of fundamental cell behaviors. The extracellular matrix's (ECM) …

Atomic force microscope (AFM) users often calibrate the spring constants of cantilevers
using functionality built into individual instruments. This calibration is performed without …

Proper force calibration is a critical step in atomic and lateral force microscopies (AFM/LFM).
