Aptamer-Based Fluorometric Ochratoxin A Assay Based on Photoinduced Electron Transfer

Aptamer-Based Fluorometric Ochratoxin A Assay Based on Photoinduced Electron Transfer

This study describes a novel quencher-free fluorescent method for ochratoxin A (OTA) detection based on the photoinduced electron transfer (PIET) between guanine and fluorophore. In the absence of OTA, carboxyfluorescein (FAM)-labeled aptamer can partly hybridize with the complementary strand of OTA...
