due to its high toxicity. Therefore, developing an ultrasensitive method for determining hydrazine in real water and biosystems is of great significance. Herein, based on coumarin dye, a turn-on fluorescent probe Cou-1-N2H4, which contains an acetyl group as the trigger unit and the fluorescence quencher, is developed. The probe can achieve a rapid (3min) and colorimetric sensing detection for hydrazine
肼作为一种强还原剂,已广泛用于许多工业产品中。然而,由于其高毒性,它是潜在的人类致癌物和环境污染物。因此,开发一种用于测定实际水和生物系统中肼的超灵敏方法具有重要意义。在此,基于香豆素染料,开发了包含乙酰基作为触发单元和荧光猝灭剂的开启型荧光探针Cou-1-N 2 H 4。该探针可快速(3分钟)进行比色传感检测,并具有极低的下限检测(11.9 nM或0.38 ppb)。更重要的是,通过定量的N 2 H 4已成功证明了探针的实用性。检测环境水样中的活细胞中N 2 H 4的生物成像。
