separsons writes "Researchers at the Lawrence Livermore National Laboratory recently unveiled a three-inch-long bio-detector than can scan for 3,000 different types of viruses and bacteria in just 24 hours. The device, dubbed the Lawrence Livermore Microbial Detection Array (LLMDA), boasts significant advantages over traditional bio-detectors, which can only identify a maximum of 50 pathogens. The three-inch-long glass slide is packed with 388,000 probes that can detect more than 2,000 viruses and 900 bacteria. The device may have huge implications in identifying agents released during biological and chemical attacks. Plus, in more everyday uses, LLMDA can ensure food, drug and vaccine safety and help diagnose medical problems. Scientists' next version of LLMDA is even more impressive: A new bio-detector will be lined with 2.1 million probes that can scan for 5,700 viruses and thousands of bacteria as well as fungi and protozoa."
