LAUSANNE, Switzerland, Jan. 28, 2020 — Time is critical when diagnosing sepsis, but the tests currently used to identify this disease can take up to 72 hours. Researchers at the Laboratory of Bionanophotonic Systems (BIOS) at École Polytechnique Fédérale de Lausanne (EPFL) have developed an optical biosensor that reduces sepsis diagnosis time from several days to a few minutes. The portable biosensor is based on nanoparticle-enhanced digital plasmonic imaging.
