'Super-resolution' Microscope Used To See Nanostructures
2013-04-29 16:09:39

Purdue University Researchers have found a way to see synthetic nanostructures and molecules using a new type of super-resolution optical microscopy that does not require fluorescent dyes, representing a practical tool for biomedical and nanotechnology research. "Super-resolution optical microscopy has opened a new window into the nanoscopic world," said Ji-Xin Cheng, an associate professor of biomedical engineering and chemistry at Purdue University. Conventional optical microscopes...

Cloud Computing Code Speeds Processing Of Data-intensive Microscopy Data
2013-02-01 10:33:43

Salk Institute In this week's Nature Methods, Salk researchers share a how-to secret for biologists: code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images. The method promises to speed research into the underlying causes of disease by making single-molecule microscopy of practical use for more laboratories. "This is an extremely cost-effective way for labs to process super-resolution images," says Hu Cang, Salk assistant...

Researchers from the Georgia Institute of Technology and University of California San Francisco have advanced scientists' ability to view a clear picture of a single cellular structure in motion. By identifying molecules using compressed sensing, this new method provides needed spatial resolution plus a faster temporal resolution than previously possible. Despite many achievements in the field of super-resolution microscopy in the past few years with spatial resolution advances, live-cell...

Michigan Tech Researcher Nears Creation Of Superlens
2012-01-09 04:37:13

A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones. No one has yet made a superlens, also known as a perfect lens, though people are trying. Optical lenses are limited by the nature of light, the so-called diffraction limit, so even the best won´t usually let us see objects smaller than 200 nanometers across, about...

Superlenses earned their superlative by being able to capture the "evanescent" light waves that blossom close to an illuminated surface and never travel far enough to be "seen" by a conventional lens. Superlenses hold enormous potential in a range of applications, depending upon the form of light they capture, but their use has been limited because most have been made from elaborate artificial constructs known as metamaterials. The unique optical properties of metamaterials, which include the...
