  How AFM works
AFM (figure 1) operates by measuring attractive or repulsive forces between a tip and the sample (Binnig et al., 1986).
The feedback loop (figure 6) consists of the tube scanner that controls the height of the entire sample; the cantilever and optical lever, which measures the local height of the sample; and a feedback circuit that attempts to keep the cantilever deflection constant by adjusting the voltage applied to the scanner.
The ability of AFM to image at atomic resolution, combined with its ability to image a wide variety of samples under a wide variety of conditions, has created a great deal of interest in applying it to the study of biological structures.

  What is AFM?
AFM stands for Atomic Force Microscopy or Atomic Force Microscope and is often called the "Eye of Nanotechnology".
AFM works by bringing a cantilever tip in contact with the surface to be imaged.
AFM has much broader potential and application because it can be used for imaging any conducting or non-conducting surface.

 AFM Safecoat
That's why for over 25 years we've been working to develop the safest, highest quality and least toxic paints and building products.
Today AFM safecoat is the leading provider of environmentally responsible, sustainable and non-polluting paints, stains, wood finishes, sealers and related green building products.
Many so-called "Zero VOC" products on the market reduce emissions that cause outdoor air pollution, but still contain a host of unregulated toxic ingredients (such as formaldehyde, ammonia, acetone, exempt solvents and odor masking agents) that cause indoor air pollution.

 AFM adjustment
The flap of the AFM is attached to a horn that swings an electrical connector along resistive track providing variable resistance depending on position of the flap and therefore on the amount of air passing through.
The spring of the AFM unit is in place to insure that the flap does not wander but is continually pressed against the air flow to provide instantaneous response to the change in the amount of air passing through.
The stronger AFM flap shifts the course of operation to leaner mixture domain, the weaker flap obviously shifts the course of operation to richer domain.

 AFM Intro
AFM is one of many techniques which fall under the Scanned Probe Microscopy (SPM) family of instruments.
Contact AFM is done by bringing the tip to a distance at which repulsive forces dominate the tip-sample interaction.
For Non-Contact AFM the force is measued by comparing the frequency and/or amplitude of the cantilever oscillation relative to the driving signal.

 AFM-type data storage
Another good thing about AFM measurements is that the contact force between the probing tip and the surface is very small - on the order of a few nN (10-10 kg) which minimizes damage to the most delicate surfaces.
It is not surprising that the idea of AFM attracted attention of the storage system designers: high resolution and accuracy of the tool, and its ability to create small indentation in the surfaces and image these indentations with the same tip seemed to be more than sufficient for the task.
AFM systems work in contact or semi-contact modes, when the deflection of the AFM cantilever is measured optically (most common technique), but could be also measured by using an integrated sensor, which changes electric resistance when deformed.

 AFM Principles
The AFM has undergone several enhancements over the years, allowing it to measure the local resistivity, temperature, elasticity, tribology, as well as allowing studies beyond the limitations of conventional optics.
The AFM works much the same way a phonograph or profilometer works only on a much, much smaller scale: a very sharp tip is dragged across a sample surface and the change in the vertical position (denoted the "z" axis) reflects the topography of the surface.
For most AFM, the height of the tip (and therefore sample) is usually monitored using a laser beam which reflects off the backside of the cantilever (a gold coating on the cantilever makes it behave like a mirror).

 AFM Applications   (Site not responding. Last check: )
Cell biologists have applied the AFM's unique capabilities to study the dynamic behavior of living and fixed cells such as red and white blood cells, bacteria, platelets, cardiac myocytes, living renal epithelial cells, and glial cells.
AFM imaging of cells usually achieves a resolution of only 20-50 nm, not sufficient for resolving membrane proteins but still suitable for imaging other surface features, such as rearrangements of plasma membrane or movement of submembrane filament bundles.
Specifically, the AFM can observe the elasticity and, in fact, the viscosity of samples ranging from live cells and membranes to bone and cartilage.

 Introduction to Atomic Force Microscopy (AFM)
The atomic force microscope (AFM), or scanning force microscope (SFM) was invented in 1986 by Binnig, Quate and Gerber.
In the case of the AFM, the probe is a tip on the end of a cantilever which bends in response to the force between the tip and the sample.
The first AFM used a scanning tunnelling microscope at the end of the cantilever to detect the bending of the lever, but now most AFMs employ an optical lever technique.

 AFM
Applications of Atomic Force Microscopy (AFM) are ubiquitous in all bioscience areas that require surface characterization of molecules (nucleic acids, lipids, proteins…), cells (live mammalian cell cultures, bacteria…), tissues (bone, cartilage, dentin, cornea…), and biomaterials.
As a result, the AFM allows for high resolution, three-dimensional imaging of samples in conditions close to their native state.
In order to maximize the performance of an AFM, it is important to understand how an AFM works and how each component of the microscope plays a role in the optimization of these results.

 Scientific Graphics for AFM/SPM/SEM microscopy
AFM microscopy is getting more and more sophisticated with introduction of the combined AFM instruments that support multiple modes of data acquisition.
Modern AFM can produce multiple data sets taken at several modes such as: height, phase, modulated force, optical microscopy, luminescence, Raman spectroscopy, electrical (Kelvin potential), magnetic, etc. The amount of data to be analyzed together might be large so that the traditional 2D and 3D visualization is not adequate any longer for scientist.
To address the needs of modern AFM microscopy ScienceGL has developed specific 3D graphics for multiple layer data taken at different AFM modes.

The two most commonly used modes to image samples with an AFM are the contact and the intermittent contact mode (tapping mode).
Additionally to the imaging the AFM can be used to determine elastic moduli and with a vibrating cantilever even viscous moduli of soft matter by recording force-distance curves.
To avoid damages of living cells during the measurement and in order to have clearly defined geometrically properties of the probe for the following calculation of the moduli, we glue a polysterene bead to the tip of the cantilever.
