AI Technical Summary
Technical Problem
The existing nitrogen-doped fluorescent carbon dots have poor selectivity and sensitivity to trivalent iron (Fe3+), and it is impossible to achieve efficient detection.
Method used
Red nitrogen-doped fluorescent carbon dots (N-CDs) were prepared by hydrothermal method using erythromycin and L-isoleucine as raw materials. This carbon dot only responds to Fe3+ in the presence of different metal ions.
Benefits of technology
High selectivity and sensitivity detection of Fe3+ is achieved, which can be used for quantitative detection of Fe3+ and has application potential for multicolor cell imaging in the field of biomedical science.

Abstract
The invention discloses nitrogen-doped fluorescent carbon dots for ferric iron detection and a preparation method and application thereof, and belongs to the technical field of chemical detection. The nitrogen-doped fluorescent carbon dots are prepared by taking erythromycin and L-isoleucine as raw materials through a hydrothermal method. The red nitrogen-doped fluorescent carbon dots (N-CDs) with high yield (70%) are prepared through hydrothermal treatment of L-isoleucine and erythromycin. The obtained N-CDs have high selectivity and sensitivity to Fe < 3 + >, and have wide application prospects in sensors, detection platforms and environment monitoring systems. Based on excellent biocompatibility and low toxicity of N-CDs, the N-CDs can be successfully used for multicolor cell imaging, and has great potential in the field of biomedicine.
