Quantifying the nanomechanical properties of soft-matter using multi-frequency atomic force
microscopy (AFM) is crucial for studying the performance of polymers, ultra-thin coatings …

The mechanical properties of hydrogels are of importance in many applications, including
scaffolds and drug delivery vehicles where the release of drugs is controlled by water …

The interaction between a rapidly oscillating atomic-force-microscope tip and a soft-material
surface is described with use of both elastic and viscous forces in a moving-surface model …

We present an alternative approach to pump-probe spectroscopy for measuring fast charge
dynamics with an atomic force microscope (AFM). Our approach is based on coherent …

We perform a comparative study of dynamic force measurements using an Atomic Force
Microscope (AFM) on the same soft polymer blend samples in both air and liquid …

We study high-speed friction on soft polymer materials by measuring the amplitude
dependence of cyclic lateral forces on the atomic force microscope (AFM) tip as it slides on …

Investigating visco-elastic forces at the nanometer-scale is important to the characterization
of soft materials. A quantitative force measurement can be obtained using an atomic force …
