Expansion Microscopy: Key things to know

Advances in biology and medicine are not just in the form of new devices or products. Rather, new methodologies are blazing trails, and microscopy techniques are no exception! In a recent article, Wassie et al describes a new optical microscopy technique that they describe as “expansion microscopy.” They discovered that preserved biological specimens could be physically expanded in an isotropic fashion through a chemical process. Expansion microscopy, shortened to “ExM,” enables nanoscale imaging of biological […]
