DOUGLAS FARMER, SENIOR EDITOR [email protected]Researchers from Washington University in St. Louis have found a mechanism to efficiently and accurately measure the point spread functions (PSFs) of the position of molecules, called variance upper bound (VUB). They believe this will someday aid scientists and clinicians as they look to understand what is happening at the molecular level in the body. The researchers specifically used fluorescent molecules to bind with amyloid fibers and measure their differences in structure. As it turns out, in so doing, they found a way to bypass typical limitations associated with single-molecule...Read full articleRelated content from Photonics MediaArticlesAlgorithm Targets Microscope ResolutionScientists have used various approaches to improve spatial resolution in fluorescence microscopy.
