Formaldehyde (FA) is widely used as an adhesion promoter and dyeing aid in industrial production. Ingestion of a certain amount of formaldehyde may cause corrosive burns in the mouth, throat, and digestive tract. Therefore, it is very necessary to use simple and effective detection methods to ensure human health and food safety. Herein, a novel fluorescent probe NFD based on naphthalimide for the detection of formaldehyde in food was designed and synthesized. The probe had a remarkable fluorescence response to formaldehyde at 554 nm. And it exhibited fascinating advantages of good selectivity, high sensitivity, and low detection limit. In addition, the solid sensor prepared by loading the probe on the filter paper was successfully realized the visual detection of liquid and gaseous formaldehyde. More importantly, the probe possessed excellent stability in the detection of formaldehyde in real food samples and animal serum samples.
甲醛（FA）在工业生产中广泛用作黏合剂和助染剂。摄入一定量的甲醛可能会导致口腔、喉咙和消化道腐蚀性灼伤。因此，使用简单有效的检测方法来确保人类健康和食品安全是非常必要的。在此，设计并合成了一种基于萘酰亚胺的新型荧光探针 NFD，用于检测食品中的甲醛。该探针在 554nm 处对甲醛有显著的荧光响应。并且，它表现出良好的选择性、高灵敏度和低检测限等迷人的优点。此外，通过将探针负载在滤纸上制备的固体传感器成功地实现了液体和气体甲醛的可视化检测。更重要的是，该探针在检测实际食品样品和动物血清样品中的甲醛时具有优异的稳定性。
