Abstract
We developed a nanoplasmonic sensor employing extraordinary optical properties of 30nm-thick ultrathin Ag nanogratings. An order-of-magnitude improvement in the temporal and spatial resolutions was achieved relative to state-of-the-art nanoplasmonic sensors, for comparable detection resolutions.
