Zero-background fluorescence probe enables precise detection of hazardous hydrazine

Hydrazine (N2H4) is a highly toxic organic amine that can spontaneously ignite or explode when exposed to strong oxidants, air, or high temperatures. It is classified as a Class B2 hazardous substance by the U.S. Environmental Protection Agency, the World Health Organization, and the International Agency for Research on Cancer, which underscores the significant risks it poses, highlighting the need for effective detection methods.
