Hydrazine detection in the gas state and aqueous solution based on the Gabriel mechanism and its imaging in living cells

A new probe based on the Gabriel mechanism was designed and first used for hydrazine detection with high selectivity against other amines in aqueous solution. Importantly, the probe could be used for gas-state discrimination of hydrazine with different concentrations. Additionally, probe 1 could also be applied for the imaging of hydrazine in living cells.
