This experiment shows 275, 5um, 1024x1024 pixel image, taken at 17Hz (170um/s tip velocity). Each image is analyzed using the blind reconstruction method in the NanoScope SW to determine the estimated tip diameter, and is plotted versus image number. The results show that over this entire 270 image sequence, the tip remains extremely sharp and virtually

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 tried to showcase a lot of the ease-of-use features

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 of magnitude improvement over a conventional AFM on

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
