A new conjugated polymer-based combination probe for ATP detection using a multisite-binding and FRET strategy.

A new conjugated polymer-based ratiometric combination probe was constructed for adenosine triphosphate detection by taking advantage of a multisite-binding and fluorescence resonance energy transfer strategy. The method is rapid and highly selective, which can clearly discriminate ATP from persistent interferents such as ADP, AMP, other nucleoside polyphosphates and nucleobases.
