  • PeakForce Tapping Bibliography

    PeakForce Tapping is a Bruker exclusive AFM mode released in 2010 that is already featured in hundreds of peer reviewed publications. This post contains a list of all PeakForce Tapping publications in a .txt file (formatted according to the BiBTeX format: ) and a second...

  • Re: Is it possible to modify the parameters in Auto adjustment procedure (ICON AFM, PeakForce QNM method)?

    I'm afraid that there is currently no way to set limits as you suggest. That is a good idea. I will ask software if we can do this! --Bede

  • Re: What is the physical meaning for “Inphase”, “Quadrature” channels in ScanAsyst mode?

    Q: Is there any output in the QNM mode which is comparable to the phase imaging in tapping? What is the difference between Inphase and Quadrature outputs, in layman terms? Why does the quadrarture seem to have more noise? A: The inphase is the Rcos(theta) and quadrature is the Rsin(theta) outputs from...

  • Bacteriorhodopsin imaging with Bruker Dimension FastScan and Peak Force Tapping

    See this new Nano Letters paper on ultrahigh resolution imaging and mechanical mapping of bacteriorhodopsin. I thought I would post this link as nice example of the science that can be done using the AFMs high resolution imaging power, coupled with the inherent...

  • New Applications Note on ScanAsyst and PeakForce Tapping

    We just published a new Applications Note for download here: PeakForce Tapping™ (PFT) and ScanAsyst™ (SA) are two Atomic Force Microsocope (AFM) imaging techniques that have been recently introduced by Bruker. In this application...

  • Re: Dimension FastScan

    For those interested in dynamic imaging with the AFM: Attached is a link to a Dimesnion FastScan video of DNA taken in tapping mode in fluid at a rate 1 frame per second. We took this data in collaboration with Y. Lyubchenko, at the University of Nebraska Medical Center, as a proof of concept experiment...

  • Dimension FastScan

    Today Bruker Nano Surfaces Division announced the innovative and unique Dimension FastScan AFM, which delivers a significant breakthrough in improved imaging speed without sacrificing nanoscale resolution. The Dimension FastScan enables users to obtain usable data significantly faster than is possible...

  • Re: I need a really HARD AFM tip

    By the probe in question, I suspect you are using TappingMode. I would perhaps approach your problem from a different direction and recommend you scan with Peak Force Tapping. We have found the PFT can image with considerably less tip damage and wear. This is a discussed a bit in this post: http://nanoscaleworld...

  • Re: Using high aspect ratio probes

    Additionally, you might want to try dropping the "Engage setpoint" to 0.08V (in the "Other" controls in scan parameter list) and the engage step size to 0.5um (in the general engage parameters). This will help give a softer engage when using stiffer probes with Peak Force Tapping...

  • Re: ScanAsyst with other probes

    Tony, I don’t think you should have any problem using these probes, and the operation should not change. A key feature of ScanAsyst is its exceptional force control when compared to other modes, and we have found that this force control enables much higher resolution when imaging because tip sharpness...
