An AIEgen nano-assembly for simultaneous detection of ATP and H2S

A new aggregation-induced emission (AIE)-based fluorescence sensor, TPEPy-SS-C14, for simultaneous recognition of adenosine triphosphate (ATP) and hydrogen sulfide (H2S) has been reported via the aggregation-disaggregation mechanism. The probe self-assembles nano-structure aggregations in aqueous solution. It shows fluorescence turn-on response toward ATP for the complexation-enhanced aggregation, but leads to fluorescence quenching of H2S for cleavage the aggregations.
