Not all plaque – the fatty substance that builds up in arteries – is the same and some plaque types are more likely to rupture, which can trigger the formation of a blood clot and a blocked artery. An experimental spectroscopic/imaging technique can provide exact information about plaque components that can help guide treatment, researchers reported at the American Heart Associations Scientific Sessions 2005.
"Time-resolved laser-induced fluorescence spectroscopy or TR-LIFS can be used to accurately identify plaque with these dangerous characteristics, while the plaque still lines the walls of vessels," said lead researcher Laura Marcu, Ph.D., director of biophotonics research at the Cedars-Sinai Medical Center and associate professor at the University of Southern California in Los Angeles.
The laser pulse heats up or "excites" molecules in the plaque while researchers measure the "time" that molecules stay in the excited state. This time is specific to different types of molecules, which helps researchers determine the "exact composition of the plaque."

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
