A team from the Institute of Photonic Sciences (ICFO) has developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes. Temperature controls many of the cell's life processes, such as splitting and metabolism. A European research team led by the Institute of Photonic Sciences (ICFO), which has the Severo Ochoa mark of...

New Research Could Peg Quantum Dots As Future Of Lighting
2012-05-10 03:53:43

Researchers are looking to white-light quantum dots as the future of lighting. White-light quantum dots are ultra-small fluorescent beads of cadmium selenide that are able to convert blue light produced by an LED into a warm white light similar to an incandescent light. Vanderbilt University researchers are reporting that they have successfully boosted the fluorescent efficiency in nano crystals from an original level of three percent to as high as 45 percent.  This feat proves...

UVOST® allows rapid screening of most petroleum-based light non-aqueous phase liquids (LNAPLs). Fargo, ND (PRWEB) May 04, 2012 Dakota Technologies introduces the UVOST®, a direct-push delivered sensor that allows rapid screening of most petroleum-based light non-aqueous phase liquids (LNAPLs). This tool uses laser-induced fluorescence (LIF) technology to immediately detect sub-surface contamination without having to draw samples or wait for lab results. The UVOST responds...

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...

Discovery could lead to new methods for environmental remediation and speeding up chemical reactions A glow coming from the glassy shell of microscopic marine algae called diatoms could someday help us detect chemicals and other substances in water samples. And the fact that this diatom can glow in response to an external substance could also help researchers develop a variety of new, diatom-inspired nanomaterials that could solve problems in sensing, catalysis and environmental...

Image 1 - Proteins Shine Light On Cellular Processes
2012-03-22 04:12:05

A new design triples efficiency of cyan fluorescent proteins Scientists have designed a molecule which, in living cells, emits turquoise light three times brighter than possible until recently. This improves the sensitivity of cellular imaging, a technique where biological processes inside a living organism are imaged at high resolution. The results have been published in Nature Communications on 20 March 2012. The lead author of the publication is Antoine Royant from the Institut de...

Researchers Increase Speed Of Single-molecule Measurements
2012-03-19 04:22:15

New integrated circuit design could lead to cheaper, faster DNA sequencing As nanotechnology becomes ever more ubiquitous, researchers are using it to make medical diagnostics smaller, faster, and cheaper, in order to better diagnose diseases, learn more about inherited traits, and more. But as sensors get smaller, measuring them becomes more difficult–there is always a tradeoff between how long any measurement takes to make and how precise it is. And when a signal is very weak, the...
