*** Following on from a post in another group *** . . . Thanks for your review. I believe we agree on the assessment of the data, and in several of its interpretations, but disagree on some key conclusions. Where we agree is PeakForce Tapping is a mode that provides unique and complimentary information to existing modes. As I have mentioned before,

In the released NanoScope version today it is possible to capture the force curves for a partial image using our High Speed Data Capture function and correlate the position of those force curves with the image pixels. As the name perhaps hints, PeakForce Capture will become a more powerful feature soon. A release later this summer will extend the capability

*** Following on from a post in another group *** . . . I am also a bit remiss in posting the “PeakForce Tapping: Atomic Imaging” webinar link. It is first thing tomorrow morning so please register now - Join us at: http://goo.gl/z3l6c We will be showing more data than we have posted here - including getting atomic resolution IN AIR, as

Alex, You can find a lot of great papers on this if you do a google scholar search on Qingze Zou or Georg Schitter. Steve

We previously posted a link showing atomic defects in the Mica lattice taken in TappingMode (http://goo.gl/wvVFi). Indeed this is routine for us to do on our different platforms, on multiple samples. If you are interested in these types of experiments, please contact me offline so I can arrange for you to see them at any time. In looking at the 4 previously

PeakForce Tapping sequence highlighting unique lattice defects, as well as adsorbates. In this sequence you can also see 2 different adatoms appear on the surface and then disappear in subsequent frames.

A follow up to the previous conversation, from another forum: Thanks for bringing the references of your high resolution work into the discussion. They are as impressive now as they were then. I do have to say I am pleased that all of those experiments were completed on Bruker AFMs, particularly the Dimension Line. It is also nice to show that our systems

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
