N2 - Paper Sensor detection methods are attractive in wide analytical applications. Presented herein is a paper sensor and fluorescence methods that was firstly developed to detect curcumin (Cur) based on fluorescence resonance energy transfer (FRET) between nitrogen-doped carbon quantum dots (NCQDs) and Cur. The facile fluorescent method was demonstrated to detect Cur in the range of 0–2600 μM with a detection limit of 0.13 μM. And facile paper sensor of Cur was fabricated and displayed at concentration of 0 μM, 100 μM, 200 μM, 300 μM, 400 μM, 500 μM and 600 μM, respectively. In additions, it was realized for determination of Cur in real samples including orange juice and curry solution. Compared with the reported methods, the present method is simple, rapid and sensitive for detecting Cur.
