Large Scanning Range and Rapid AFM for Biological Cell Topography Imaging
Abstract:
The small spatial displacement of the piezo tube scanner limits the AFM(Atomic Force Microscopy) scanning range, especially when facing up to cell topography scanning. And the low dynamic property of normal AFM tube scanner tube restricts the imaging speed. In order to achieve large scanning range and rapid scanning motion simultaneously, a special atomic force microscopy is designed. The 100um scanning range is obtained by the new scanner which is composed of the flexure guide structure instead of peizo tube. Furthermore, a new acquiring image method is used to eliminating AFM nonlinearity error. Using this scanning system, some large biological cells are imaged in liquid environments with 30 lines per second.
