Optical microscopes, with the help of cell-staining to colour cells, can help us peer into the invisible world of cells. However, they only show us a 2D image of a very thin slice of tissue. But how can we see what the cells and tissue actually look like in 3D?

Dr Madleen Busse from the Technical University of Munich has been developing X-ray stains that can be used to visualise cells and tissues in 3D using cutting-edge X-ray imaging techniques developed by her colleagues Prof Franz Pfeiffer and Simone Ferstl MSc.
