Abstract
Light isacrucial tool inmedicinefordiagnosisand treatment.Newlight sourcescalledorganic light-emittingdevices (OLEDs) have been integratedwith various extracorporeal and implantabledevicestosenseorstimulatespecificcellularresponses. However, oneof thecurrent challenges remaining is todesigna transientOLEDthat functionseffectivelyandcompletelydissolves inside the human bodywhen it is no longer needed, without affectinghomeostasis.Thisworkaddresses this issuebycreating thefirst transientchitosan-basedOLED.TheOLEDis turnedon at lowvoltages andemits abright green lightwithamaximum luminanceof36cd/m2. Invitroassaysshowedthatall layersbreak downunder physiological settings, and thebiocompatibilitywas confirmedbyinvivotests.Thechitosan-basedOLEDrepresentsa breakthroughintransientelectronicsandadvances implantable light-basedbiomedical applications
