Yes, indeed in addition to PeakForce Tapping, we have also demonstrated atomic resolution in TappingMode on FastScan, Icon, and MultiMode. The image below show a Tapping example on Mica using the MultiMode 8 and a SNL+ cantilever (60um long). In all these cases, we did not redesign any of the systems, and used them in the standard configurations - but

The cycle averaging of Tapping limits performance because 1) the high resolution tip-sample interaction only occurs when the tip is close to the sample, and this is a fraction of the cycle, and 2) at low imaging forces, the effects of long range forces dominate the cycle. (This is also why atomic Tapping images are done in fluid. . . eliminate the long

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

No problem. Please just always include the link to the source, and that it comes from Bruker. Best, Steve
