Discovery of a highly selective and ultra-sensitive colorimetric fluorescent probe for malononitrile and its applications in living cells and zebrafish
addition, the probe has good selectivity and anti-interference, and only has good recognition effect on malononitrile. The color of the probe changed from light green to light pink for naked eye observation after the reaction. Most importantly, the probe can be used for the biological imaging of living cells and zebrafish. These results indicate that the probe can be used for the detection of malononitrile
