Diabetics May One Day Measure Blood Glucose With Laser Light, Not Needles
2013-10-26 05:12:16

[ Watch the Video: Lighting The Way To Better Diabetic Glucose Monitoring ] redOrbit Staff & Wire Reports - Your Universe Online German researchers have reportedly developed a novel, non-invasive method that uses infrared laser light to help monitor the blood glucose levels of people suffering from Type 1 and Type 2 diabetes. Currently, diabetes patients use electronic devices that require a small drop of blood in order to determine sugar levels. However, the new device would...

New photoacoustic technique detects multiple nerve agents simultaneously To warn of chemical attacks and help save lives, it's vital to quickly determine if even trace levels of potentially deadly chemicals–such as the nerve gas sarin and other odorless, colorless agents–are present. U.S. Army researchers have developed a new chemical sensor that can simultaneously identify a potentially limitless numbers of agents, in real time. A paper describing the system has been published...

Researchers have developed multiple techniques and procedures to detect cancer cells during the earliest stages of the disease or after treatment. But one of the major limitations of these technologies is their inability to detect the presence of only a few cancer cells. Now, a research collaboration between the University of Missouri-Columbia and Mexico's Universidad de Guanajuato shows that pulsed photoacoustic techniques, which combine the high optical contrast of optical tomography...

New technique may help restorers identify decades-old pigments A team of McGill chemists have discovered that a technique known as photoacoustic infrared spectroscopy could be used to identify the composition of pigments used in art work that is decades or even centuries old. Pigments give artist's materials color, and they emit sounds when light is shone on them. "The chemical composition of pigments is important to know, because it enables museums and restorers to know how the paints will...

ANN ARBOR, Mich., April 16 /PRNewswire/ -- Endra Life Sciences today announced the launch of the Nexus 128, a preclinical photoacoustic computed tomography (CT) scanner for small animal imaging. The system is used for simple, fast, non-invasive quantification of tumor vasculature and other physiological parameters for preclinical research. The Nexus 128 makes in vivo quantification of tumor vasculature possible without the need for contrast agents and helps preclinical researchers gain...

Using a laser and a device that converts reflected light into sound, researchers at the Department of Energy's Oak Ridge National Laboratory can detect explosives at distances exceeding 20 yards. The method is a variation of photoacoustic spectroscopy but overcomes a number of problems associated with this technique originally demonstrated by Alexander Graham Bell in the late 1880s. Most notably, ORNL researchers are able to probe and identify materials in open air instead of having to...
