Everything about microscopes, dyes and superresolution
For all the talk about criteria and definitions, measuring the resolution of a microscope is more nuanced than you’d think. The scales at which microscopes operate today are subject to noise and background that obscure and distort signals. What you use for the measurement can make a big difference. The second article in our "Resolution" series. Details >
How the donut changed the world
For over a century, we stood at the edge of microscope resolution and cursed the inexorable blur of diffracted light. Instruments improved, but the fog never lifted. Then, one man stopped trying to control how light behaves. Armed with a donut-shaped laser beam, he instead commanded where it shines and untethered resolution forever. Details >
Are you surprised that the very nature of light caps the resolution that we can achieve in microscope images? Luckily, there are workarounds to this limit. These workarounds push the amount of detail in an image by manipulating precisely where and when fluorophores are allowed to emit. As such, they provide us with a completely new set of tools to shrink the distance between two points while still being able to resolve them. Details >
