Natelson Lab pioneers technique to measure heat, dissipation at very small scales You can touch a functioning light bulb and know right away that it's hot. Ouch! But you can't touch a single molecule and get the same feedback. Rice University researchers say they have the next best thing -- a way to determine the temperature of a molecule or flowing electrons by using Raman spectroscopy combined with an optical antenna. A new paper from the lab of Douglas Natelson, a Rice professor of physics...

Harvard scientists push SRS microscopy to new levels of spatial, temporal precisionA novel type of biomedical imaging, made possible by new advances in microscopy from scientists at Harvard University, is so fast and sensitive it can capture "video" of blood cells squeezing through capillaries.Researchers led by Harvard's Brian G. Saar, Christian W. Freudiger, and X. Sunney Xie describe the work this week in the journal Science.The new technique, based on stimulated Raman scattering (SRS),...

A paper by researchers at the National Institute of Standards and Technology (NIST) may breathe new life into the use of a powerful"”but tricky"”diagnostic technique for cell biology. The paper,* appearing this week in the Biophysical Journal, demonstrates that with improved hardware and better signal processing, a powerful form of molecular vibration spectroscopy can quickly deliver detailed molecular maps of the contents of cells without damaging them. Earlier studies have...

Using nanotechnology and a patented signal enhancing technique developed at the University of Georgia, UGA researchers have discovered a rapid, sensitive and cost-effective method to detect and identify a number of rotavirus strains and genotypes in less than one minute with greater than 96 percent accuracy. In their study, Ralph A. Tripp and Jeremy D. Driskell, researchers in the College of Veterinary Medicine's department of infectious diseases, and Yiping Zhao and Richard Dluhy,...

COLLEGE STATION -- Engineers and applied physicists have laid the foundations for a new type of "plug and play" laser -- the Raman injection laser -- and in the process, several key innovations in laser technology. The device combines the advantages of nonlinear optical devices and semiconductor injection lasers with a compact design, and may one day lead to wide-ranging applications in imaging and detection. Published in the Feb. 24th issue of Nature, the proof of concept model was developed...
