A full-field hard-x-ray microscope at SSRL has successfully imaged samples of biological and environmental origin at 40 nm resolution. Phase contrast imaging of trabeculae from a female mouse tibia, loaded in vivo to study the effects of weight-bearing on bone structure, revealed a complex network of osteocytes and canaliculi. Imaging of cordgrass roots exposed to mercury revealed nanoparticles with strong absorption contrast. 3D tomography of yeast cells grown in selenium rich media showed internal structure.
美国斯坦福直线加速器中心（SSRL）的全场硬X射线显微镜已成功以40纳米的分辨率对生物和环境来源的样本进行成像。对一只雌性小鼠胫骨小梁进行的相衬成像（该小鼠在体内加载以研究负重对骨骼结构的影响）揭示了一个由骨细胞和小管组成的复杂网络。对暴露于汞的互花米草根的成像显示出具有强烈吸收对比度的纳米颗粒。对在富硒培养基中生长的酵母细胞进行的三维断层扫描显示了其内部结构。
