  • Title: A new fluorescent probe for colorimetric and ratiometric detection of sulfur dioxide derivatives in liver cancer cells.
    Author: Li DP, Wang ZY, Cui J, Wang X, Miao JY, Zhao BX.
    Journal: Sci Rep; 2017 Mar 28; 7():45294. PubMed ID: 28349998.
    Abstract:
    A new ratiometric fluorescent probe was constructed with hemicyanine and 7-nitrobenzofurazan for detection of sulfur dioxide derivatives (HSO3-/SO32-). The ratiometric response mode could be attributed to the efficient FRET (Förster resonance energy transfer) platform. The probe exbihited some desirable properties including fast response (within 2 minutes), good selectivity and high sensitivity. Moreover, the probe could detect endogenous HSO3- in liver cancer cells rather than normal liver cells, implying the diagnosal potential of the probe.
