Abstract

We discuss the potential of OLEDs for biomedical applications. Specifically, we present our latest research on near-infrared (NIR) OLEDs based on phosphorescent compounds. Beginning with fundamental synthetic concepts, we delve into how the design of the emitting layer influences the emission spectrum and efficiency, aiming for optimal device design. We also showcase the application of these NIR OLEDs in photobiomodulation (PBM). Following this, we share our advancements in internal PBM using OLED catheters, which incorporate ultrathin OLEDs. Additionally, we discuss the outcomes of animal experiments, focusing on rats with type-II diabetes that have been treated with duodenal OLED PBM.
