摘要: A new molecularly imprinted polymer (MIP), which acts as a fluorescence nano-sensing material, has been developed for the highly selective and sensitive optosensing of tocopherol (TP). The material was constructed by anchoring MIP layer on 1-vinyl-3-octylimidazolium ionic liquid (IL)-modified CdSe/ZnS quantum dots (QDs) copolymerization. Here, IL first introduced to surface QDs using one-step modification electrostatic interactions prepare uniform MIPs. more strongly quenched TP than non-imprinted was, indicated that QDs@IL@MIP could recognize corresponding without need inducers derivatization.
