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 with other commercial AFM systems. It is simply sound engineering and a reflection of know-how from Bruker scientists and engineers, having realized a significant breakthrough in scientific instrumentation.

I invite you to personally experience the capabilities of Dimension FastScan, it truly opens new possibilities and simply delivers what many have discussed for many years past.

Check out the video and learn about all the details: http://www.bruker.com/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.

Here we use the enhanced bandwidth of the system coupled specific with resolution and tracking settings to increase the frame rate. The entire sequence is 2100 images, and in those you can see the DNA moving back and forth randomly (ie it is not dominated by the AFM forces) nor cut or damaged over that sequence. Sacrificing resolution for speed to create AFM videos is one of the many ways a way you can apply increased bandwidth to reveal new information in your AFM experiments. Other good video sites below. Enjoy!

Interesting debate going on linked-in. Reposting here for comment as well.

What qualifies a as a high speed AFM?

There has been a lot of discussion on what it takes to claim high speed. Should a baseline criteria be to demonstrate at least an order of magnitude improvement over a conventional AFM on a standard sample? The venerable diffraction grating has always served as a normalizing standard of baseline performance, additionally is readily available to all. Boring, potentially. Telling, yes. Agreed? Here is the Dimension FastScan data, 30um on a 180nm grating at 11Hz.
