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 […]
