Here, a novel molecularly imprinted photopolymer was prepared using CsPbBr₃ quantum dots as the fluorescence source, TpPa-2 as substrate for selective solid fluorescence detection of patulin (PAT). TpPa-2 can promote efficient recognition of PAT due to its unique structure and significantly improve the fluorescence stability and sensitivity. The test results showed that the photopolymer exhibited large adsorption capacity (131.75 mg/g), fast adsorption ability (12 mins), superior reusability and high selectivity. The sensor proposed had good linearity for PAT in the range of 0.2-20 ng/mL and was applied to the analysis of PAT in apple juice and apple jam with a limit of detection as low as 0.027 ng/mL. Therefore it maybe a promising method for solid fluorescence detection of trace PAT in food analysis.

_{在这里，使用 CsPbBr 3}量子点作为荧光源，TpPa-2 作为底物制备了一种新型分子印迹光聚合物，用于棒曲霉素 (PAT) 的选择性固体荧光检测。TpPa-2由于其独特的结构可以促进PAT的高效识别，显着提高荧光稳定性和灵敏度。测试结果表明，光聚合物表现出大吸附容量（131.75 mg / g），快速吸附能力（12分钟），优异的可重复使用性和高选择性。所提出的传感器对 PAT 在 0.2-20 ng/mL 范围内具有良好的线性，并应用于苹果汁和苹果酱中 PAT 的分析，检测限低至 0.027 ng/mL。因此，它可能是食品分析中痕量 PAT 固体荧光检测的一种很有前途的方法。
