Summary: A improved two-step strategy is proposed to synthesize high-quality lignin-based carbon dots (LCDs) with high quantum yield and stable fluorescence properties. The successful co-doping of nitrogen and sulfur elements leads to a high quantum yield of 45.05% for the LCDs. Additionally, the LCDs exhibit superior selectivity and sensitivity for Fe3+ and have potential applications in chemical sensing and bioimaging.

Summary: Amino acids are crucial in various physiological processes and the accurate monitoring of their metabolism remains a challenge. This study successfully synthesized multi-color emission carbon dots (CDs) that demonstrated bright and steady luminescence. These CDs exhibited low cytotoxicity and excellent multi-color cell imaging ability. Specifically, chiral red emissive CDs (R-L-CDs) were able to quickly identify specific amino acids in water and biological samples. The introduction of a smart phone color recognizer application improved the accuracy of visual detection. Overall, these findings have far-reaching prospects for the application of R-L-CDs as biosensors.
