Europium-containing carbon dots (Eu-CDs) for ratiometric fluorescence determination of oxytetracycline and tetracycline antibiotics differentiation

Key Points

• Ratiometric fluorescence measurement enables distinct differentiation between oxytetracycline and tetracycline.
• Data reveals a clear distinction with a high sensitivity threshold for both antibiotics in real samples.
• Method involves europium-containing carbon dots to enhance fluorescent signals and accuracy of detection.
• Potential applications include improved monitoring of antibiotic presence in various environments, raising awareness about antibiotic resistance.
