Fluorescence resonance energy transfer between an anionic conjugated polymer and a dye-labeled lysozyme aptamer for specific lysozyme detection.
Surface charge switch of a 6-carboxyfluorescein (FAM) labeled lysozyme aptamer from negative to positive upon lysozyme binding triggers fluorescence resonance energy transfer (FRET) between an anionic conjugated polymer and the aptamer, which provides a convenient method for lysozyme detection in biological media with high sensitivity and selectivity.
