Preparation method and application of lanthanide coordination polymer coated silver nanocluster for visual field detection of tetracycline

Abstract

The invention belongs to the technical field of environment and food detection, and particularly provides a preparation method and application of lanthanide coordination polymer coated silver nanoclusters for tetracycline visual field detection. According to the invention, the AMP-Eu coated AgNCs is prepared by using the AMP-Eu coated AgNCs, so that the visual, sensitive and accurate detection of tetracycline is realized. The preparation of the AMP-Eu-coated AgNCs can be completed at room temperature, the ratio type fluorescent probe can be conveniently prepared by a one-pot method by virtue of the self-assembly characteristic of the lanthanide coordination polymer, the whole preparation process is simple, convenient and efficient, and the repeatability is excellent. Besides, the visual test paper can be prepared in a simple soaking mode, quantitative detection of tetracycline in an actual sample can be completed in combination with mobile phone software, and a convenient and feasible scheme is provided for on-site rapid detection.
