U.S. Researchers Develop New Biological Detector

Researchers at the U.S. Lawrence Livermore National Laboratory in California have developed a type of “biological smoke detector” capable of detecting a biological attack, according to a study published last week in Analytical Chemistry (see GSN, Jan. 4).

The detector can continuously monitor the air for bacteria, viruses and toxins. The device uses two tests to reduce the likelihood of false positives (American Chemical Society press release, Jan .5).
