A biosensor specific to nitric oxide is realized by integrating an organic light‐emitting diode, a photodetector, and a sensing hydrogel film. Two organic filters are also used to reduce the influence of the excitation light on the output photocurrent of the photodetector. The response time is less than 5 min.
