Application of Flexible OLED Display Technology to Point-of-Care Medical Diagnostic Testing

This paper presents a new concept combining flexible organic light-emitting diode (OLED) display technology with fluorescent biorecognition microarray technology to fabricate point-of-care immunobiosensors. Our approach is designed to leverage commercial OLED display technology to reduce pre-functionalized biosensor substrate costs to pennies per cm² combined with leveraging the display industries ability to manufacture an immense number of low-cost consumer electronic products annually. For this work, we demonstrate that our new approach using high brightness flexible OLED display technology combined with a charge integrating readout circuit and optical filters can offer point-of-care diagnostic sensitivity at or below 10 pg/mL, which approaches the lower limit of detection (LLOD) of typical clinical laboratory instrumentation.
