Expansion Microscopy Has Transformed How We See the Cellular World

How physically magnifying objects using a key ingredient in diapers has opened an unprecedented view of the microbial world.

When you slip a slide under a microscope, a system of glass lenses magnifies the object of your attention — a microbe, for example. But even with the largest zoom on a classic compound optical system, scientists struggle to make sense of finer details, which can be further obscured when tough cell walls make it difficult to inject dyes that help identify structures. Now, rather than invest in…
