Technique has potential to detect cancerHank HoganA team of researchers wants to use gold to mark a spot where a tumor in the earliest stage of breast or prostate cancer exists. To that end, a group from the University of Texas Medical Branch in Galveston, from Fairway Medical Technologies in Houston, from the Mayo Clinic College of Medicine in Jacksonville, Fla., and from the University of Michigan in Ann Arbor, used engineered gold nanorods as a contrast agent for a laser optoacoustic imaging system. In the in vivo optoacoustic experiment, gold nanorods were injected subcutaneously into the lower abdomen and detected from the back...Read full articleRelated content from Photonics MediaARTICLESChirality and Nanotechnology Speed Up Light-Based Drug ScreeningA team of international collaborators has introduced a drug-screening technique that relies on nanostructure chirality as its fundamental property.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookDetectors: CCDs for Life-Science Applications: The CCD camera is becoming the imaging method of choice in biological laboratories for its resolution, versatility and ease of use. Choosing the best CCD for a given application, however, requires knowing how basic chip parameters affect performance.Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications. Electronic cameras based on CCD technology are used in...Photonics HandbookLaser Measurement Systems: Best Practices: When purchasing a laser, learning how to apply, troubleshoot, and evaluate that device is very important.Given the pace at which technology advances, there always seems to be a learning curve.
