AI Technical Summary
Technical Problem
Existing methods for detecting tetracycline antibiotics have low sensitivity and are complex to operate, making it difficult to perform on-site testing.
Method used
EuTPE-MOF materials were prepared by reacting europium salts, benzoic acid, and terephthalic acid derivatives with small molecules of p-aminophenylethylene to form a three-dimensional structure, which was then combined with CdS quantum dots to form CdS@EuTPE-MOF fluorescent materials. High-sensitivity detection was achieved by utilizing the photoinduced electron transfer mechanism.
Benefits of technology
It improves the sensitivity of tetracycline antibiotic detection, simplifies the operation process, and enables highly sensitive on-site detection.
