Oregon State University researchers combined diatoms (a type of single-celled photosynthetic algae) with self-assembled plasmonic nanoparticles to create a low-cost sensor capable of detecting miniscule amounts of protein or other biomarkers.
Optical biosensors are important in health care for such applications as detecting levels of blood glucose or the presence of antibodies. They are also used for chemical detection in environmental protection.
Existing biosensors often require high-cost… read more
