A new turn-on fluorescent probe, named as NaFP was structured with hydrazine group as a recognition site for detecting formaldehyde (FA) in living cells. The probe NaFP has large turn-on signal and high selectivity for FA. In addition, the results of cell imaging experiments indicate that NaFP could image exogenous/endogenous FA in living cells.

一种用于活细胞内源性甲醛成像的新型高选择性荧光探针

以肼基为识别点，用于检测活细胞中的甲醛（FA），构造了一种名为NaFP的新型开启式荧光探针。NaFP探针具有较大的开启信号，并且对FA的选择性高。此外，细胞成像实验的结果表明NaFP可以对活细胞中的外源/内源FA进行成像。
