Diatom Biosensor Could Detect Chemicals in Water

Facebook X LinkedIn Email
SEQUIM, Wash., March 30, 2012 — A biosensor made of fluorescent proteins that are embedded in the shell of microscopic marine algae called diatoms could help detect chemicals in water samples. The device could help produce nanomaterials that can solve sensing, catalysis and environmental remediation problems. The fluorescent biosensor was developed by researchers at the Department of Energy’s Pacific Northwest National Laboratory, who were inspired by previous research showing that it is possible to insert proteins in diatom shells through genetic engineering. Diatoms make up the bulk of phytoplankton, the plant...Read full article
