The development of stable fluorescent sensors for toxic pollutants and drugs is meaningful to the environment and public health. In this work, nitrogen-doped graphene quantum dots (N-GQDs) were facially synthesized by a one-step hydrothermal method using soluble starch and l-arginine as carbon and nitrogen sources in pure water at 190 °C for 4 h. The as-synthesized N-GQDs were well characterized and displayed blue fluorescence emission at 445 nm with excellent pH stability, salt tolerance, thermostability, photobleaching resistance and reproducibility.

- - A new fluorescent probe called 4-AHBI was created, which is based on a modified benzimidazole structure.
- - This probe showed very high sensitivity in detecting triphosgene, with a detection limit as low as 0.08 nM, and it was able to specifically identify triphosgene among other similar chemicals.
- - Researchers also developed test strips containing 4-AHBI, allowing for practical and easy sensing of triphosgene in real-world applications.
