Cationic conjugated polymer-based FRET aptasensor for label-free and ultrasensitive ractopamine detection

A label-free fluorescence resonance energy transfer (FRET) platform based on cationic conjugated polymers and aptamers for ultrasensitive and specific ractopamine detection was constructed. This method exhibited a wide linear range from 0.05 to 500 μM and a low limit of detection of 47 nM, which mak...

Summary:A label-free fluorescence resonance energy transfer (FRET) platform based on cationic conjugated polymers and aptamers for ultrasensitive and specific ractopamine detection was constructed. This method exhibited a wide linear range from 0.05 to 500 μM and a low limit of detection of 47 nM, which make it an attractive assay platform for foodborne doping. A label-free fluorescence resonance energy transfer (FRET) platform based on cationic conjugated polymers and aptamer has established for ultrasensitive and specific ractopamine (RAC) detection.
