Multimodal Sensors (IMAGE) Rice University Caption Rice University scientists use tiny gaps between gold electrodes to simultaneously perform electronic and optical measurements of the same molecule. These scanning electron images show electrodes and gaps on a silicon chip. The color insets show optical signals due to the chip (top) and a gap (bottom). Credit D.
