Lemon yellow is a kind of common food additive. Excessive use of food additives and metabolized free radicals in blood may bring potential harm to human health. In this study, we synthesized a kind of green luminescent fluorescent carbon dots by one-step method, which can effectively detect lemon yellow and this kind of material is sensitive to pH. More importantly, this material can effectively remove superoxide anion and hydroxyl radical. The synthesis method is simple and some unique functions will make this material have greater potential applications.

Fluorescent Carbon

Fluorescent carbon dots with blue, green, and red emissions were rapidly prepared from modified pine needles through microwave irradiation in a one-pot reaction. The fluorescence intensity and emission versatility for a carbon source were experimentally optimized. The reaction times were under 10 min and the reaction temperatures were lower than 220 °C. Potential applications of magnetic fluorescence-linked immunoassays of carcinoembryonic antigen (CEA) and tumor necrosis factor-alpha (TNF-α) were presented. The detection limits for CEA and TNF-α (3.1 and 2.8 pg mL−1, respectively) are lower than those presented in other reports, whereas the linear ranges for CEA and TNF-α (9 pg mL−1 to 18 ng mL−1 and 8.5 pg mL−1 to 17 ng mL−1, respectively) are wider than those presented in other reports. Magnetic immunoassays with fluorescent CDs prepared from pine needles can enable rapid, sensitive, and selective detections for biochemical analysis.
