A hydrogenated amorphous silicon photodiode is used for the integrated, real-time detection of chemiluminescent reactions in solution. The light emission at 425 nm resulting from the horseradish peroxidase-catalyzed oxidation of luminol is detected by a p-i-n amorphous silicon photodiode operated at zero bias. The sensitivity achieved is in the range of nanomole of horseradish peroxidase per liter.
