Expansion microscopy allows imaging of cell membranes in super resolution – News-Medical.net

For the first time ever, expansion microscopy allows the imaging of even the finest details of cell membranes. This offers new insights into bacterial and viral infection processes.
Expansion microscopy (ExM) enables the imaging of cells and their components with a spatial resolution far below 200 nanometres. For this purpose, the proteins of the sample under investigation are cross-linked into a swellable polymer. Once the interactions between the molecules have been destroyed, the samples can…
