Organic Light-Emitting Diodes Applications in Biomedical Therapy Mechanisms Clinical Studies and Challenges

This paper mainly discusses the use of Organic Light-Emitting Diodes (OLEDs) in photodynamic therapy (PDT) and photobiomodulation (PBM) for curing typical basal cell carcinoma, Bowen disease, actinic keratosis. The innovative PDT method has several advantages than the traditional onesOLEDs plays an essential role in reducing the pain for patients according to case studies and patients can barely experience uncomfortable feelings during the therapeutic process than before. It is also much more light-weighted and can be more closely attached to skin. Therefore, this device can also be applied to the elderly and infants at any location and at any time without going to the hospital. However, there are still some remaining issues such as the chronic pain, which is hard to be eliminated due to the conflict situation since reactive oxygen species (ROS) will cause major pain, however, if completely removing ROS will decrease the effect of PDT. Therefore, more researches need to be done in this field.
