A new autoinductive cascade employing benzoyl fluoride as a latent source of fluoride is reported for signal amplification and optical detection of fluoride. The autoinduction leads to a maximum 4-fold signal enhancement for each fluoride generated, as well as a self-propagating cycle that generates three fluorophores for each single fluoride released. A two-step integrated protocol creates a more rapid autoinductive cascade than previously reported, as well as a highly sensitive diagnostic assay for the ultratrace quantitation of a phosphoryl fluoride nerve agent surrogate.

用于氟化物光学传感的新型自感级联：在磷酰氟神经毒剂检测中的应用

使用苯甲酰氟作为潜在氟化物源的新型自感应级联被报道用于氟化物的信号放大和光学检测。自动诱导导致产生的每种氟化物的最大 4 倍信号增强，以及为每个释放的单个氟化物产生三个荧光团的自传播循环。两步集成协议创建了比以前报告的更快速的自感应级联，以及对磷酰氟神经毒剂替代品的超痕量定量的高度灵敏的诊断分析。
