IV Drug Detection (IMAGE) Optica Caption a) The surface of the new drug sensor was made from a flexible plastic sheet covered with gold domes. b) This is a close-up of the sensor's surface taken with a scanning electron microscope (SEM). Each of the domes visible in the image is less than one millionth of a meter wide. c) The sensor incorporated with a plastic cell that can be connected in series with IV tubing used to bring drugs to a patient. d) A schematic illustration of the new IV drug sensor. A laser is focused onto the sensor's surface, over which the IV-delivered drugs flow. Credit Hsin-Yu Wu, Nano Sensors Group, University of Illinois Usage Restrictions Must include caption & credit.
