A crucial tool in the evolution of scientific capability in bioscience, the fluorescence microscope has allowed a generation of scientists to study the properties of proteins inside cells. Yet as human capacity for discovery has zoomed to the nanoscale, fluorescence microscopy has struggled to keep up. Now, a team that includes UGA engineer Peter Kner has developed a microscope that is capable of live imaging at double the resolution of fluorescence microscopy using structured illumination....

CSIRO has patented an improved microscopy method for measuring the shapes and sizes of proteins which could help scientists create new pharmaceuticals that are a better match for the proteins they target. The method, called Differential Aberration Correction (DAC) microscopy, measures distances at the molecular level in two and three dimensions using conventional fluorescence microscopy. A special feature of the new method, written up recently in the Journal of Microscopy, is that it allows...

University of Utah physicists and chemists developed a new method that uses a mirror of tiny silver "nanoparticles" so microscopes can reveal the internal structure of nearly opaque biological materials like bone, tumor cells and the iridescent green scales of the so-called "photonic beetle." The method also might be used for detecting fatigue in materials such as carbon-fiber plastics used to build the latest generation of aircraft fuselages, tails and wings, says John Lupton, an associate...

U.S. scientists say they've developed a nanoparticle system that allows microscopes to view the internal structure of nearly opaque biological materials. University of Utah researchers said their new nanotechnology can scan materials such as bones and tumor cells and the method might be used for detecting fatigue in materials such as carbon-fiber plastics. Associate Professor John Lupton and Assistant Professor of chemistry Michael Bartl said optical microscopes are limited in how much detail...

Einstein research helps scientists see cancer and other cells at the molecular level Remarkable new tools that spotlight individual cellular molecules are transforming biomedical research. Scientists at the Gruss Lipper Biophotonics Center at the Albert Einstein College of Medicine of Yeshiva University have spearheaded their use in a series of papers, including one published Sunday in the online version of Nature Methods. These new tools are photoactivatable fluorescent proteins (PAFPs) and...

Thanks to a new "super-resolution" fluorescence microscopy technique, Harvard University researchers have succeeded in resolving the features of cells as miniscule as 20-30 nanometers (nm), an order of magnitude smaller than conventional fluorescence light microscopy images, according to a presentation at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008, in San Francisco."Super resolution" microscopy techniques enable scientists to visualize cells laterally...

By Hoppe, Adam D Shorte, Spencer L; Swanson, Joel A; Heintzmann, Rainer ABSTRACT Analysis of cellular pathways requires concentration measurements of dynamically interacting molecules within the three- dimensional (3D) space of single living cells. Forster resonance energy transfer (FRET) microscopy from widefield, from confocal, and potentially from superresolution microscopes can access this information; however, these measurements are distorted by the inherent 3D blurring of optical...
