Stanford scientists have developed a fluorescence imaging technique that allows them to view the pulsing blood vessels of living animals with unprecedented clarity. Compared with conventional imaging techniques, the increase in sharpness is akin to wiping fog off your glasses.
Nano-photonics expert Shawn Yu-Lin, professor of physics at Rensselaer Polytechnic Institute and a member of the university's Future Chips Constellation and Smart Lighting Engineering Research Center, has been selected as a fellow of the American Association for the Advancement of Science (AAAS). Lin is one of 702 newly selected fellows recognized for their scientifically or socially distinguished efforts to advance science or its applications. The announcement will be made in the Nov. 30, 2012, issue of the journal Science.
Tufts University School of Engineering researchers have demonstrated silk-based implantable optics that offer significant improvement in tissue imaging while simultaneously enabling photo thermal therapy, administering drugs and monitoring drug delivery. The devices also lend themselves to a variety of other biomedical functions.
School of Engineering and Applied Sciences (SEAS) can absorb 99.75% of infrared light that shines on it. When activated, it appears black to infrared cameras.
Using a combination of the new tools of metamaterials and transformation optics, engineers at Penn State University have developed designs for miniaturized optical devices that can be used in chip-based optical integrated circuits, the equivalent of the integrated electronic circuits that make possible computers and cell phones.
New research at King's College London may lead to improved solar cells and LED-displays. Researchers from the Biophysics and Nanotechnology Group at King's, led by Professor Anatoly Zayats in the department of Physics have demonstrated in detail how to separate colours and create 'rainbows' using nanoscale structures on a metal surface. The research is published in Nature's Scientific Reports.
Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.
A device that looks like a tiny washboard may clean the clocks of current commercial products used to manipulate infrared light.
Supercharging is a technique no longer confined to automotive enthusiasts.
In many respects, metamaterials are supernatural. These manmade materials, with their intricately designed structures, bend electromagnetic waves in ways that are impossible for materials found in nature.
