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...

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...

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...

Dynamic heating and cooling AFM measurements can be challenging because the temperature changes can induce considerable drift both in position, and force control. Below is a video showing a high speed imaging dynamic experiment from 60 C to -2 C. Tip scanning greatly simplifies the temperature control...

See this new Nano Letters paper on ultrahigh resolution imaging and mechanical mapping of bacteriorhodopsin. http://pubs.acs.org/doi/abs/10.1021/nl202351t. 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...

PS: A good test of the robustness of a system is to scan Celgard® in different orientations; here is an even faster video (23Hz) where the mesh is perpendicular to the scan. Enjoy, Steve

I was reading an AFM site and saw a contrived claim trying to make a comparison that was >50% off the benchmark and thought it would be a good topic to open up for discussion. The comment was to the effect of: by scanning at a slower scan speed we are actually going faster because our poor scanner...

It’s good to see some community attempts at replicating the performance of the Dimension FastScan. The screen shot below is of a 1um, 512x512, 22Hz, Video of Celgard® taken with the Dimension FastScan (Video link at end). This demonstration is over twice as fast as the 10Hz video we show above...

Nothing like a quality sample preparation (thanks Natalia!) and an awesome AFM to get great soft-sample high-speed images (thanks Shuiqing & Adam!). This new video shows height and phase of freshly prepared Celgard; the images are at ~20um/s (or 10Hz scan rate for 1um images): In the video, we also...

Interesting debate going on linked-in. Reposting here for comment as well. **** Normal 0 false false false EN-US X-NONE X-NONE 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...
