Ratiometric Fluorescent Probe

We designed a near-infrared ratiometric (2.1 to 15.3, I608/I735) fluorescent probe with a quick response (20 s) based on cyanine polyene derivatives. This probe can detect endogenous hypochlorous acid in HepG-2 cells and determine the hypochlorous acid content in 84 disinfectant and other actual samples.

Naked Eye Detection

A turn-on fluorescent probe for cysteine with high selectivity was designed and synthetized. The probe can be used for “naked-eye” detection of Cys with an obvious color change from yellow to colorless. The probe could be applied for Cys detection in real human serum.

The ‘C–CN’ bond cleavage was applied to the recognition of N2H4 for the first time; the obvious change in color could be used for “naked-eye” detection; the corresponding detection limit was found to be 5.81 × 10−8 M (1.65 ppb); the probe could be applied for N2H4 detection in real water samples.
