Impex Complex

Cell nuclei are surrounded by a membrane pierced by protein assemblies called nuclear pore complexes which regulate trafficking of molecules in and out of the nucleus. This study precisely tracks in 3D single molecule cargo crossing the pore, using a strategy called MINFLUX nanoscopy, and reveals overlapping paths in and out

Scientists Break Optical Limits With Quantum Dot-Powered Nanoscopy - Science News

A powerful new microscopy technique unveils hidden nanoscale light interactions, offering a glimpse into physics that conventional tools cannot resolve. Over the past ten years, advances in nanofabrication have made it possible to shape materials at scales as small as 10 nanometers and even down to individual atoms. These capabilities have pushed nanophotonics into a […] Read more about this…

Passive nanorheology measurements

What do marshmallows, jelly (or Jell-O), cream cheese and Chinese soup dumplings have in common?  They are often made with gelatin.  Gelatin is derived from the skin and bones of cattle and pigs through the partial hydrolysis of collagen.  Gelatin is a physical hydrogel meaning that it consists of a three-dimensional network of polymer molecules in which a large amount of water is absorbed, as…

New fluorescent DNA label reveals nanoscopic cancer features

Researchers have developed a new fluorescent label that gives a clearer picture of how DNA architecture is disrupted in cancer cells. The findings could improve cancer diagnoses for patients and classification of future cancer risk.

Nobel Prize in Chemistry Awarded to Scientists for Microscope Breakthrough

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…
