A new class of sensors that can detect multiple biological and chemical threats simultaneously with unprecedented performance may soon be within reach, thanks to the establishment of a multimillion dollar research center led by Georgia Institute of Technology engineers. DARPA will fund the two-year, $4.3 million center as one of its Centers in Integrated Photonics Engineering Research, which investigate innovative approaches that enable revolutionary advances in science, devices or systems. For its center, Georgia Tech will work with researchers from Emory and Yale universities, from MIT and from the University of California, Santa Cruz. The team also includes industry collaborators Rockwell Collins Inc. of Cedar Rapids, Iowa; Kotura Inc. of Monterey Park and Santur Corp. of Fremont, both in California; and NanoRods LLC of Germantown, Md.
