AI Technical Summary
In existing technologies, the detection methods for sulfadiazine suffer from high costs, require specialized operation, and have poor stability of biological receptors. Furthermore, the poor orderliness of the imprints on MOF/MIPs materials leads to suboptimal analytical performance.
A template-derived boron affinity imprinting strategy was adopted to prepare the derivatized template SDZ-CD via Schiff base reaction, and FP@B-MOF@MIP material was constructed on a paper substrate. The paper-based imprinted material FP@B-MOF@MIP with ordered cavities was prepared by free radical polymerization and detected by colorimetry.
It achieves convenient, sensitive, and rapid visual detection, with low cost and simple operation. It can efficiently identify and enrich trace amounts of sulfadiazine in complex food matrices, with an imprint factor of 5.6, significantly improving detection performance.
