Method slashes quantum dot costs by 80 percent
In an important advance toward the large-scale manufacture of fluorescent quantum dots, scientists at Rice University have developed a new method of replacing the pricey solvents used in quantum dot synthesis with cheaper oils that are commonplace at industrial chemical plants.   view more (2005-09-08)

Slight Fluorescence Gives Hope For Recovery
Stomach ulcer not only aches, it also fluoresce. Russian researchers believe that the brighter the fluorescence is, the less chances the patient has to do without the operation.   view more (2005-02-22)

Structuring polymers by laser
Microstructured polymer components are often used to direct light in optical devices. As an alternative to mechanical processes, laser light can also be used to produce the microscopic relief structures, and even to remove them without contact. With a flash of blue-green light, the show begins.... view more (2004-05-14)

Argonne researcher studies what makes quantum dots blink
In order to learn more about the origins of quantum dot blinking, researchers from the U.S. Department of Energy's Argonne National Laboratory, the University of Chicago and the California Institute of Technology have developed a method to characterize it on faster time scales than have previously... view more (2007-10-05)

The search for new applications for laser light beams
Light can blind or distort colours, or confuse one with chiaroscuros. But it can have greater usefulness if its properties, characteristics, how it is created, etcetera are better understood.   view more (2006-05-30)

Laser blasts will reveal structures and dynamics of molecules in the fastest events in nature
A new £2 million Research Centre at the University of York will provide unprecedented information on how molecules change, helping scientists understand the structure and dynamics of liquids, proteins and even our DNA. The York Centre for Laser Spectroscopy and Photochemistry opened today (29... view more (2003-10-27)

Fine-tuning lasers to destroy blood-borne diseases like AIDS
