摘要：
A molecularly imprinted photonic hydrogel (MIPH)-based sensor which combines molecular imprinting with photonic crystal technology was constructed and used for the detection of dibutyl phthalate (DBP) in alcoholic beverages. Under optimal conditions, the response time of the MIPH sensor for DBP was 3 min, the diffraction peak displacement of MIPHs showed a good linear relationship with DBP concentration ranging from 0.01 to 0.1 mg/L (R2 = 0.992 0), and the detection limit of DBP was 0.01 mg/L (RSN = 3). The sensor was used to detect DBP in baijiu samples, revealing that the spiked recoveries of DBP were 95.60%-103.20%.Experimental results showed that the sensor has the advantages of simple operation, fast response, high selectivity and low cost, and has a broad application prospect in the safe and rapid screening and detection of harmful substances in alcoholic beverages. © 2022, China Food Publishing Company.
