Observation of biological specimens using soft X-ray microscope
نویسندگان
چکیده
Biological specimens were observed using a soft X-ray microscope constructed at the Ritsumeikan synchrotron radiation center BL12. The spatial resolution of the microscope using an X-ray wavelength of 2.4nm was estimated to be 75nm from the edge response. Three kinds of diatoms were observed and ultrastructures of approximately 100nm could be clearly resolved. Two kinds of bacteria and red blood cells of a chicken were observed and their intensity distributions of whole cells were clearly observed. Furthermore, the image contrast of red blood cells was compared by taking the X-ray image using an iron L-absorption edge.

X-ray holographic microscopy using photoresists
Gabor x-ray holograms of biological specimens and of test objects that display <56-nm resolution are presented. This spatial resolution is more than an order of magnitude smaller than what has been achieved previously in x-ray holography. The holograms were recorded on photoresist using 2.57-nm soft x rays from the X-17t undulator at the National Syncrotron Light Source at Brookhaven National L...
متن کاملHigh-resolution computed tomography with a compact soft x-ray microscope.
Computed tomography based on high-resolution soft x-ray microscopy utilizes the natural contrast for biological specimens provided by the water window (lambda = 2.4 - 4.4 nm) and the high resolving power of zone plate objectives. It is capable of revealing the 3D structure of biological specimens at sub-visible-microscopic resolution. To date, the technique has only been available at synchrotro...
متن کاملThree-Dimensional X-ray Observation of Atmospheric Biological Samples by Linear-Array Scanning-Electron Generation X-ray Microscope System
Recently, we developed a soft X-ray microscope called the scanning-electron generation X-ray microscope (SGXM), which consists of a simple X-ray detection system that detects X-rays emitted from the interaction between a scanning electron beam (EB) and the thin film of the sample mount. We present herein a three-dimensional (3D) X-ray detection system that is based on the SGXM technology and de...
متن کاملSoft X-ray microscopy with a cryo scanning transmission X-ray microscope: I. Instrumentation, imaging and spectroscopy.
We have developed a cryo scanning transmission X-ray microscope which uses soft X-rays from the National Synchrotron Light Source. The system is capable of imaging frozen hydrated specimens with a thickness of up to 10 microm at temperatures of around 100 K. We show images and spectra from frozen hydrated eukaryotic cells, and a demonstration that biological specimens do not suffer mass loss or...
متن کاملDirect Machining of Inner Reflecting Surface for a Soft X-ray Microscope
INTRODUCTION A soft X-ray microscope can be used to investigate hydrated specimens, particularly living cells, with a high resolution about several times better than that of a visible light microscope. It can also extend to material science, plasma fusion research, magnetic research, environment science, and so on. The reflecting optics used in a soft X-ray microscope requires supersmooth surfa...
