Chemical
and Biological Sensors
Novel photoluminescence-based chemical and biological sensors that are structurally integrated with an organic light emitting device (OLED) excitation source are being developed. Examples include oxygen, hydrazine, and glucose sensors as well as immunoassays.
The sensing component is fabricated on one side of a glass or plastic substrate, while the light-source required to excite the photoluminescence (i.e., an OLED array) is fabricated on the other side. Such integrated sensors will be compact, battery-operated, inexpensive (eventually disposable), automated, and remotely-operated. This integration addresses the need for miniaturized devices in medical and environmental testing, high-throughput drug discovery, and detection of inorganic gases, volatile organic compounds (VOCs), pathogens, warfare agents, and in-vivo biological compounds and organisms. In developing the devices, we optimize the performance of the sensing components and the OLEDs, to maximize their dynamic range, sensitivity, and stability, while minimizing power consumption. Sensor (micro) arrays for multianalyte detection are also being developed.
