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.

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

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.

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.

1993
Abstract This chapter discusses atomic force microscopy (AFM), focusing on the methods for atomic force detection. Although the force detection always requires a cantilever, there are two types of modes: the static mode and the dynamic mode. The general design and the typical method of manufacturing of the cantilevers are discussed.

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

Can atomic force microscopy tips be inspected by atomic force microscopy?
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1991An attempt has been made to image prospective tips by atomic force microscopy. The apex of mounted diamond fragments and of traditional metallic tips was investigated by the same diamond probe. The peculiar tip–tip configuration allowed to search for the effect of sample rotation on the images.
