Previously high‐resolution soft x‐ray microscopy has only been possible with synchrotron sources. Here, the first successful attempts at using a scanning transmission x‐ray microscope with a laser‐plasma source are reported. Spatial resolutio

Using a Fresnel zone plate we demonstrate for the first time the direct visualization by x-ray microscopy of suboptical regularity in a biological specimen, namely the 65-nm axial periodicity of tendon collagen. This resolution test demonstrates a re

A scanning x-ray microscope has been built at the Daresbury synchrotron radiation source and used to obtain images at soft x-ray wavelengths (∼2–4 nm). The focusing element of the microscope is a zone plate, fabricated by a contamination writing

Elemental imaging via scanning transmission x‐ray microscopy (STXM) and scanning fluorescence x‐ray microscopy (SFXM) has been used to image calcium deposits in cartilage. In the case of STXM, 0.1 μm thick sections were imaged to investigate the

Summary Myofibrils, the contractile organelles from striated muscles, have been examined in the X-ray microscope to determine the effect of radiation on their function and structure. Using X-rays of energy 350–385 eV in the water window we find tha

The future of x-ray microscopy lies mainly in its potential for imaging fresh, hydrated biological material at a resolution superior to that of light microscopy. For the image to be accepted as representing the cellular organization of the living cel

X rays have been used extensively in the study of hard tissue such as bone. The x rays used are typically of energy 50 keV, which have an absorption depth of approximately 1.5 cm in hard tissue. These x rays are used for creating x-ray shadowgraphs (

The use of soft x-ray imaging is considered for the determination of the repeating macromolecular structure of biological fibers (e.g., collagen and muscle), within the available image resolution and subject to the effects of radiation damage. A comp

X-ray microscopy has the potential for imaging relatively thick, wet, and ultimately viable biological material at resolutions greater than those attainable in the optical microscope. Achieving this potential necessitates the development of a chamber
