Three-dimensional quantitative force maps in liquid with 10 piconewton, angstrom and sub-minute resolutions.
We develop a bimodal force microscopy method to map the three-dimensional force fields and their time-evolution on a variety of solid-water interfaces. The force maps show an oscillatory decaying force perpendicular to the solid surface with a 0.3 nm periodicity. The technique enables the three-dimensional imaging and mapping of the hydration layers and forces on mica and protein GroEL surfaces...
متن کاملThe Model Analysis of a Complex Tuning Fork Probe and Its Application in Bimodal Atomic Force Microscopy
A new electromechanical coupling model was built to quantitatively analyze the tuning fork probes, especially the complex ones. A special feature of a novel, soft tuning fork probe, that the second eigenfrequency of the probe was insensitive to the effective force gradient, was found and used in a homemade bimodal atomic force microscopy to measure power dissipation quantitatively. By transform...
متن کاملRepulsive bimodal atomic force microscopy on polymers
Bimodal atomic force microscopy can provide high-resolution images of polymers. In the bimodal operation mode, two eigenmodes of the cantilever are driven simultaneously. When examining polymers, an effective mechanical contact is often required between the tip and the sample to obtain compositional contrast, so particular emphasis was placed on the repulsive regime of dynamic force microscopy....
متن کاملBimodal atomic force microscopy imaging of isolated antibodies in air and liquids.
We have developed a dynamic atomic force microscopy (AFM) method based on the simultaneous excitation of the first two flexural modes of the cantilever. The instrument, called a bimodal atomic force microscope, allows us to resolve the structural components of antibodies in both monomer and pentameric forms. The instrument operates in both high and low quality factor environments, i.e., air and...
متن کاملOptimization of phase contrast in bimodal amplitude modulation AFM
Bimodal force microscopy has expanded the capabilities of atomic force microscopy (AFM) by providing high spatial resolution images, compositional contrast and quantitative mapping of material properties without compromising the data acquisition speed. In the first bimodal AFM configuration, an amplitude feedback loop keeps constant the amplitude of the first mode while the observables of the s...
