I posted this answer to a question on another forum, and thought I would repeat it here. You can see the question at: http://goo.gl/yLoCF *** Thanks for your comments, and we, along with several others who posted in these forums, are in agreement that atomic resolution imaging using Tapping in fluid is not new, despite recent attempts to package it

Another great advantage of PeakForce Tapping, particularly when imaging at the atomic scale, is you can obtain a forces curve for any pixel in the image. Here are two examples of force distance curves collected during Peak Force Tapping imaging. One set of approach / retract curves was collected on calcite and the other was collected on mica. The mica

I had a comment on another forum that I thought I would repeat here about our work with respect to that of Professor Frieder Mugele at Twente University. Professor Mugele has taken amazing atomic images and force curves on Gibbsite using the MultiMode. He and Dan Ebling have a paper in process, which should be out soon. We are also writing a joint Application

An atomic resolution image of Calcite, this time taken on he Dimension Icon (90um scanner, large sample platform, SNL+ probe) showing the height and stiffness channels. (In the software, this is called Modulus, however, at the atom level, modulus is not defined since it is a continuum property. Here we simply note that areas where the force curve slope

Achieving atomic resolution with AFM has been a goal of the community since the invention of the technique. There are a number of great results from academic laboratories (Fukuma et. al., Hoogenboom et. al., Gross et. al.) that have demonstrated this by systematically lowering the noise of their systems - ie moving to restrictive small sample platforms

Image of the cleavage plane of calcite taken with the Dimension FastScan using a standard cantilever (SNL+, 60um) in water. In the image you can see two crystal planes (brown and blue) separated by the dissolving crystal front (red). We have overlaid the atomic model of the oxygen atoms in the calcite on the lower plane, and there you can see the zig
