Background:
Developing convenient, rapid fluorescent sensors for antibiotic detection is imperative for public health.
Results:
In this article, four new metal-organic frameworks with dual-state emitters (DSEs) have been synthesized named as CUST-670∼673. CUST-670∼673 exhibit good structural stability and luminescence, serving as fluorescence sensors for tetracycline antibiotics with fluorescence color from blue to yellow-green. Portable visual detection cotton swabs and writable MOFs membranes were developed for rapid, easy detection of tetracyclines in real foods (e.g., milk, beef) and simple information encryption. The recovery rate of this method (98.1-100.3 %) is comparable to that of HPLC, with a relative standard deviation (RSD) below 1.42 %.
Significance:
This work highlights MOFs' promising applications in food detection and information encryption, providing an experimental basis for subsequent practical use.
