متن کاملLaboratory cryo soft X-ray microscopy.
Lens-based water-window X-ray microscopy allows two- and three-dimensional (2D and 3D) imaging of intact unstained cells in their near-native state with unprecedented contrast and resolution. Cryofixation is essential to avoid radiation damage to the sample. Present cryo X-ray microscopes rely on synchrotron radiation sources, thereby limiting the accessibility for a wider community of biologis...
متن کاملSoft x-ray microscopy with coherent x rays (invited)
The Soft X-ray Undulator beamline at the NSLS supports a soft x-ray imaging program including scanning transmission microscopy, scanning photoemission microscopy, Gabor and Fourier transform holography, and large angle diffraction. Zone plates from an LBL Center for X-ray Optics/IBM collaboration are used as optical elements. The current instrumentation of the beamline and the experimental stat...
متن کاملRecent developments in X-ray projection microscopy and X-ray microtomography applied to materials science
After a long period of sleeping, there is recently a spectacular revival of X-ray microscopy due to the progress in X-ray sources (synchrotron radiation), X-ray optics, and X-ray detectors. However most of the attempts in this field concern the use of soft X-rays to observe, with an improved resolution, biological specimens in their wet environment. In opposition to these trends, we try to demo...
متن کاملBiological imaging by soft x-ray diffraction microscopy.
We have used the method of x-ray diffraction microscopy to image the complex-valued exit wave of an intact and unstained yeast cell. The images of the freeze-dried cell, obtained by using 750-eV x-rays from different angular orientations, portray several of the cell's major internal components to 30-nm resolution. The good agreement among the independently recovered structures demonstrates the ...
