In this work, we propose a fluorescence detector based on a dual-gate photosensitive thin-film transistor (DGPTFT) for rapid on-chip detection of zinc coproporphyrin I (ZnCP-I), a biomarker of amniotic fluid embolism (AFE). Working in the subthreshold region, the detector can achieve high sensitivity and low noise. In the preliminary study, the detection… (More)
