First X-ray Nanofluorescence Tomography of Single Bacterial Cell


The elemental distribution and nanostructure of single E. coli cell were co-localized simultaneously using X-ray fluorescence (XRF) nanotomography and ptychography using a sub-15 nm beam. This multimodal approach presents new possibilities in understanding subcellular biochemistry in individual organelles, which are usually analyzed at the population level.
