Abstract

We report an on-chip peroxyoxalate chemiluminescence (PO-CL) assay for antioxidant capacity determination with optical detection based on our highly compact and sensitive integrated detectors made from solution processed thin-film organic photodiodes (OPDs). We compared the performance of our OPDs for on-chip antioxidant capacity screening with that of commercial photomultiplier tubes (PMTs). The results show excellent consistency between the two detection methods.
