ABSTRACT
Glutathione (GSH) plays a crucial role in several physiological processes, including anti-oxidation and heavy metal detoxification. GSH is produced endogenously in the human body and can also be obtained through diet. The development of fast, highly sensitive, and multi-application fluorescent probes remains a challenging task. In this study, we have designed and synthesized a coumarin-based fluorescent probe (NFRF) for the sensitive and rapid detection of GSH in 100 % aqueous solution. By loading probe NFRF on the filter paper, the real-time visual detection of GSH is achieved in both daylight and fluorescence modes, providing a convenient, economical and rapid on-site detection tool. Probe NFRF could be used for the detection of GSH in real samples, with recoveries rates of 81.74 %-115.12 %. Notably, the probe imaged changes in GSH concentrations in oxidative stress environments and during ferroptosis. This work provides a prospective method for GSH detection in food and complex biological systems.
