A Mn-doped ZnS quantum dots (QDs) based nanosensor for selective phosphorescent determination of patulin (PAT) was synthesized with 6-hydroxynicotinic acid (6-HNA) as dummy template via a surface molecular imprinting sol-gel process. FTIR and XRD indicated the successful graft of molecularly imprinted polymer (MIP) onto crystal QDs. Binding tests revealed that the MIP-QDs presented higher selectivity, adsorption capacity and mass transfer rate than non-imprinted polymers, demonstrating a specific recognition for PAT among competitive mycotoxins and its analogues with the imprinting factor of 2.02. The MIP-QDs could recognize PAT in a linear range of 0.43-6.50μmolL(-1) with a detection limit of 0.32μmolL(-1) and a correlation coefficient (R(2)) of 0.9945. Recoveries of 102.9-127.2% with relative standard deviations <4.95% were achieved in apple juice samples which were in good agreement with high-performance liquid chromatography (HPLC) (P>0.05). The results indicated a simple phosphorescent nanosensor for PAT detection in complex matrix.
