An nPoint motion control or positioning system is comprised of four elements: Piezo actuators providing motion Mechanical translation mechanism (stage) Position sensor Control electronics to maintain the desired position To realize positioning at nanometer levels of precision, these four elements need to be carefully designed and optimized. The desired attributes of a nanopositioner are extremely […]
A nanopositioner is a mechanical stage that consists of a movable component inside a rigid frame. The movable and static portions are electrodischarge machined (EDM) from a monolithic block and connected by flexure “hinges.” The movable component can move in any or all of three translational axes, as well as in angular axes such as […]
TappingMode™ image of indentation patterns on Parafilm® acquired with a MultiMode® AFM. Patterns were produced using LiftMode®. Scan size = 10 μm; large indentation pitch = 2.0 μm; small pitch (arrow) = 200 nm.
AFM cantilever force, f, plotted versus distance, h, from normal (green) and cancerous (red) cell bodies. Cancerous cells show significantly different force behavior compared to normal cells (highlighted by the circle). Data were collected in force-volume mode with a Dimension 3100 AFM with an NPXY100Z25A scanner from nPoint. Image adapted from Iyer et al; Nature […]
“We use the nPoint scanner pretty much all the time on our Dimension system to allow us to accurately position the probe for the nano thermal analysis”. Kevin Kjoller, VP of Research, Engineering and Applications, Anasys Instruments
TappingMode™ image of pentacene dendrites on a silicon dioxide substrate acquired with a MultiMode® AFM. Scan size = 11 µm. Image courtesy of Frisbie Group, University of Minnesota. 30µm scan of a lithography pattern created by charge deposition on Si sample. An Agilent 5100 AFM retrofitted with a 100×100µm nPoint scanner was used. Image courtesy […]
