Electron Holography Produces First Image of a Single Protein
Previously, if you wanted to look at a single-chained protein, you needed X-rays. This was bad news for biologists, whose lively samples were destroyed or damaged by such intense light. Now, by exploiting the short de Broglie wavelength of slow electrons, you can finally look at single proteins with sub-nanometer resolution. This is good news for disease fighters and medicine designers!
