摘要
In the paper, hydrothermal carbon spheres (HTCs) are functionalized by the 3-aminobenzeneboronic acid (3-APBA) as a fluorescence sensor. The modification carbon spheres (3-APBA-HTCs) have shown excellent selectivity and sensitivity for efficient determination of L-tryptophan (L-Trp). The fluorescence sensor can selectively achieve the "On-Off" switchable functionality for L-Trp at an extremely low detection limit of 0.50 x 10(- 5) mol/L.
