Nanophotonic Sensors Monitor Processes In Living Cells

A large-scale biosensor developed using nanoplasmonic material is able to accommodate a large number of cells on a single substrate and monitor cell proliferation in real time. The nanoplasmonic material allows for long-term cell survival and unaltered cellular responses. “Usually, when you put live cells on a nanomaterial that material is toxic and it kills the cells. However, using our material, cells survived for over seven days,” said researcher Nikhil Bhalla from the Okinawa Institute of Science and Technology (OIST).
