Acoustic Microscopy by Atomic Force Microscopy
Applied Physics Letters, 1994We have constructed an atomic force microscope enabling one to image the topography of a sample, and to monitor simultaneously ultrasonic surface vibrations in the MHz range. For detection of the distribution of the ultrasonic vibration amplitude, a part of the position-sensing light beam reflected from the cantilever is directed to an external knife ...

Capillary force in atomic force microscopy
The Journal of Chemical Physics, 2004Under ambient conditions, a water meniscus generally forms between a nanoscale atomic force microscope tip and a hydrophilic surface. Using a lattice gas model for water and thermodynamic integration methods, we calculate the capillary force due to the water meniscus for both hydrophobic and hydrophilic tips at various humidities.

Hyphenating Atomic Force Microscopy
Analytical Chemistry, 2014Atomic force microscopy can be readily combined with complementary instrumental techniques ranging from optical to mass-sensitive methods. This Feature highlights recent advances on hyphenated AFM technology, which enables localized studies and mapping of complementary information at surfaces and interfaces.

Nanofabrication with Atomic Force Microscopy
Journal of Nanoscience and Nanotechnology, 2004Atomic force microscopy (AFM) was developed in 1986. It is an important and versatile surface technique, and is used in many research fields. In this review, we have summarized the methods and applications of AFM, with emphasis on nanofabrication. AFM is capable of visualizing surface properties at high spatial resolution and determining biomolecular ...

Atomic Force Microscopy of Viruses
2019Atomic force microscopy employs a nanometric tip located at the end of a micro-cantilever to probe surface-mounted samples at nanometer resolution. Because the technique can also work in a liquid environment it offers unique possibilities to study individual viruses under conditions that mimic their natural milieu.

Atomic Force Microscopy of Viruses
2013Atomic force microscopy (AFM) makes it possible to obtain images at nanometric resolution, and to accomplish the manipulation and physical characterization of specimens, including the determination of their mechanical and electrostatic properties. AFM has an ample range of applications, from materials science to biology.

Atomic Force Microscopy of Proteins
2019Atomic force microscopy (AFM) enables imaging of surface-deposited proteins and protein structures under physiological conditions, which is a benefit compared to ultra-high vacuum techniques such as electron microscopy. AFM also has the potential to provide more information from the phase in tapping mode or from functional AFM modes.

Nanorheology by atomic force microscopy
Review of Scientific Instruments, 2014We present an Atomic Force Microscopy (AFM) based method to investigate the rheological properties of liquids confined within a nanosize gap formed by an AFM tip apex and a solid substrate. In this method, a conventional AFM cantilever is sheared parallel to a substrate surface by means of a lock-in amplifier while it is approaching and retracting from
