Biological sample-preparation procedures have been developed for imaging human chromosomes under cryogenic conditions. A new experimental setup, developed for imaging frozen samples using beamline I13 at Diamond Light Source, is described. This manuscript describes the equipment and experimental procedures as well as the authors' first ptychographic reconstructions using X-rays.
Rapid and efficient biological sample preparation and pretreatment are crucial for highly sensitive, reliable and reproducible molecular detection of infectious diseases. Herein, we report a self-powered, integrated sample concentrator (SPISC)...
