Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very high-resolution type of scanning probe microscopy, with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit.

Nanotribology, Nanomechanics and Materials Characterization Studies
08 Jun 2009 | | Contributor(s):: Bharat Bhushan
Fundamental nanotribological studies provide insight to molecular origins of interfacial phenomena including adhesion, friction, wear and lubrication. Friction and wear of lightly loaded micro/nano components are highly dependent on the surface interactions (few atomic layers). Nanotribological...

Gas Damping of Microcantilevers at Low Ambient Pressures
out of 5 stars
03 Nov 2008 | | Contributor(s):: Rahul Anil Bidkar
This seminar will present a theoretical model for predicting the gas damping of long, rectangular silicon microcantilevers, which are oscillating in an unbounded gaseous medium with the ambient pressures varying over 5 orders of magnitude (1000 > Kn > 0.03). The work is the result of a...

SPMW Scanning Probe Acceleration Microscopy: Towards Real Time Reconstruction of Tip-Sample Forces in Tapping Mode AFM
05 Jan 2007 | | Contributor(s):: Tomasz Kowalewski
Tapping mode atomic force microscopy (TMAFM) in fluids has become an increasingly important technique, especially in studying biological samples under near physiological conditions. However, until recently the physics of tapping mode operation under fluids has not been well understood. The first...
SPMW Single molecule recognition atomic force microscopy
05 Jan 2007 | | Contributor(s)::
In molecular recognition force microscopy (MRFM), ligands are covalently attached to atomic force microscopy tips for the molecular recognition of their cognitive receptors on probe surfaces. A ligand-containing tip is approached towards the receptors on the probe surface, which possibly leads...

Oligodeoxyribonucleotide Association with Single-Walled Carbon Nanotubes
02 Aug 2007 | | Contributor(s):: Jennifer McDonald
Commercially available single-walled carbon nanotubes (SWCNTs) tend to aggregate as ropes and bundles during production making them of little use in many scientific and industrial applications. An effective technique for dispersing and solubilizing SWCNTs is required to fully utilize their...
Re-engineering a Healthy Eye Tissue to Restore Damaged Eyesight
02 Aug 2007 | | Contributor(s):: Margarita Shalaev
Age-related macular degeneration (AMD) is an eye disease that is the leading cause of blindness in the USA and Western Europe. It affects over one million people in the United States alone. One of the symptoms of AMD is a diseased Bruch’s membrane, which is an important layer in the eye. Our...
SPMW A fresh look to amplitude-modulation AFM: Force minimization, interaction measurement, and the quest for high resolution
05 Jan 2007 | | Contributor(s):: Udo D. Schwarz
Frequency modulation atomic force microscopy (FM-AFM) has been able to deliver high-resolution atomic-scale images in ultrahigh vacuum for over one decade. In addition, there have been recent reports where atomic resolution has been achieved in air and liquids using FM-AFM . Achieving...
SPMW AFM at Video Rate and Beyond
16 May 2007 | | Contributor(s):: Mervyn Miles
The particular advantages that atomic force microscopy (AFM) has over other types of microscopy are well-known, but it has the one major disadvantage of low imaging rates in conventional instruments in which each image requires typically a minute or more to collect. This has two major...
SPMW The Nanomechanics of compositional mapping in amplitude modulation AFM
05 Jan 2007 | | Contributor(s):: Ricardo Garcia
Amplitude modulation atomic force microscopy (AM-AFM) has been very successful for imaging with high spatial resolution inorganic as well as soft materials such as polymers, living cells and single biomolecules in their natural environment . The ability of AM-AFM to separate topography from...
