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

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
