Chaos in Atomic Force Microscopy
Physical Review Letters, 2006Chaotic oscillations of microcantilever tips in dynamic atomic force microscopy (AFM) are reported and characterized. Systematic experiments performed using a variety of microcantilevers under a wide range of operating conditions indicate that softer AFM microcantilevers bifurcate from periodic to chaotic oscillations near the transition from the ...

Scanning in atomic force microscopy
2009 IEEE International Conference on Robotics and Automation, 2009In this paper, we present an adaptive scanning approach for atomic force microscopy (AFM) imaging. Our simulation results demonstrate that this new approach can achieve approximately one order of magnitude better scanning efficiency over current scanning method.

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.

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

Current Protocols in Microbiology, 2008
AbstractThe atomic force microscope (AFM) is an important tool for studying biological samples due to its ability to image surfaces under liquids. The AFM operates by physical interaction of a cantilever tip with the molecules on the cell surface. Adhesion forces between the tip and cell surface molecules are detected as cantilever deflections.

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 ...

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.

Atomic Force Microscopy of the Proteasome
2005The proteasome should be an ideal molecule for studies on large enzymatic complexes, given its multisubunit and modular structure, compartmentalized design, numerous activities, and its own means of regulation. Considering the recent increased interest in the ubiquitin-proteasome pathway, it is surprising that biophysical approaches to study this ...

Atomic Force Microscopy and Proteins
Protein & Peptide Letters, 2002This review briefly introduces the principles of atomic force microscopy (AFM) applied to protein samples. AFM provides three-dimensional surface images of the proteins with high resolution. The advantage of AFM for protein studies is that AFM can visualize directly the molecule under physiological conditions without previous treatment. AFM operated in

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.
