GRENOBLE, France, May 13, 2010 — CEA-Leti, a public research and technology company based in France, announced the launch of the Target-PDT project designed to increase the effectiveness of photodynamic therapy (PDT) for treating cancer by developing a novel nanocarrier-based approach. PDT is a minimally invasive treatment that destroys cancer cells with a combination of a photoactive drug known as a photosensitizer and a specific wavelength of light. When the photosensitizers are activated by the laser light, they produce a form of oxygen that destroys illuminated cancer cells. Focusing on using PDT against bone...Read full articleRelated content from Photonics MediaARTICLESNew Light-Activated Metal Compound Kills Cancer Energy SourceA team led by University of Warwick researchers is using light to activate a cancer-killing compound that attacks a vital energy source in cancer cells.

In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1. At one...Photonics HandbookLaser Safety: Important Considerations: Laser safety is nothing to scoff at; lasers can be hazardous. Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookFluorescence Lifetime Imaging: Choosing the Best Approach: Fluorescence lifetime imaging microscopy (FLIM), which measures the spatial distribution of the fluorescence decay, can be achieved either in the time or in the frequency domain. Each approach exhibits advantages and disadvantages, depending on the type of light detector and acquisition method employed.The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of...Photonics HandbookLasers: Understanding the Basics: Although lasers range from quantum-dot to football-field size and utilize materials from free electrons to solids, the underlying operating principles are always the same.
