Dark-field X-ray ptychography is an X-ray imaging technology that can exhibit a high spatial resolution even in thick materials or biological samples. It combines X-ray ptychography and X-ray in-line holography to observe weak-phase objects with a spatial resolution better than 15 nm. The method developed at the synchrotron radiation facility SPring-8 was used to observe the outline and magnetosomes of the magnetotactic bacteria MO-1 but could find broader applications in biology and the materials sciences.
