BEADS is a sample preparation system developed at Pacific Northwest National Laboratory to concentrate large volumes of environmental samples, such as soil, air, and water, into small, clean samples that can be used in biodetectors to quickly identify pathogens.

Background: Rapid detection of biological threats requires more than a detector. BEADS, short for Biodetection Enabling Analyte Delivery System, was created to fill the gap between dirty environmental samples containing potential biothreats and sensitive detectors requiring purified cell, proteins, or DNA. BEADS isolates bacteria, spores, viruses and their DNA from air, dirt, or water samples. The PNNL-developed technology is fully automated, so detectors can analyze samples and monitor for threats without requiring a person to manually prepare the samples. For more information, see PNNL?s News Releases.
