Nitrogen doped biomass derived carbon dots as a fluorescence dual-mode sensing platform for detection of tetracyclines in biological and food samples

Yanchun Jia et al.

Summary: In this study, nitrogen-doped carbon dots (N-CDs) were synthesized hydrothermally using abundantly accessible pitaya peel and 1,2-ethylenediamine as precursors. N-CDs exhibited favorable photostability and served as a multi-functional nano-sensor for detecting tetracycline antibiotics. The fluorescence of N-CDs was rapidly quenched by tetracycline and oxytetracycline, while it showed remarkable enhancement in the presence of chlortetra-cycline. Additionally, a fluorescence sensor array was developed for identifying multiple tetracycline antibiotics in real samples.
