Nobel Prize in Chemistry Awarded to Scientists for Microscope Breakthrough

Back in the late 1800s, microscopist Ernst Abbe postulated that traditional light microscopy could never achieve a higher resolution than half the wavelength of light. This presumed physical limit, known as the Abbe limit, meant that for many years, scientists believed that resolution would never be better than 0.2 micrometers. But thanks to this year’s Nobel Laureates in Chemistry, we have…

For anyone whos missed it:

This years nobel prize in chemistry is going to Stefan Hell for his outstanding work in microscopy. You might think this is not such a big deal but look at the difference in the above picture and think what it can do for science.

And for the nerds, here are the facts about the photo:

"Untangling Neurofilaments

Neurofilaments are intermediate filaments in the axon's cytoskeleton, which provide stability and determine the axon's diameter. But with widths of ~10 nm, individual neurofilaments aren't distinguishable with standard confocal microscopy (left). In contrast, STED microscopy reaches resolutions ~25 nm, and thus, can visualize the distribution of neurofilaments inside axons (right).

Image: The OGlcNAcylated epitope of the neurofilament medium subunit was immunolabeled in redifferentiated human neuroblastoma cells and visualized by standard confocal microscopy (left) or with STED microscopy (right) using a homebuilt setup, called a supercontinuum STED microscope, with a white light supercontinuum laser source operated in the visible range of the spectrum."
