Fiber bundle sensor enables multiple analyses

Collaborating groups at Lawrence Livermore National Laboratory (CA) and Tufts University (Boston, MA) have developed a prototype opticalfiber bundle sensor with multianalyte sensitivity for biomedical and environmental sensing. Using a bundle of several thousand fibers, the groups have shown the feasibility of several configurations including an eight inone sensor that can detect aluminum ions, pH, hydrocarbons, and uranyl ions.
