【 摘 要 】

In this paper, one kind of protamine sensor based on the fluorescence quenching of CDs synthesized from bagasse was fabricated. The detection conditions were optimized. The concentration of protamine in the range of 0.6-4.2 mg L-1 exhibited a linear relationship, and the limit of detection (LOD) for protamine was as low as 0.094 mg L-1. The excellent performance of the proposed probe shows that this method is sensitive, facile, rapid, low cost and eco-friendly. This study has demonstrated food waste can be converted into valuable optical sensor.
