摘要

•A surface molecularly imprinted polymer (PS-co-PMAA@VSMIP) was prepared.•A hollow structured surface molecularly imprinted polymer (HVSMIP) was prepared.•Both PS-co-PMAA@VSMIP and HVSMIP were visible-light-responsive.•HVSMIP performed better than PS-co-PMAA@VSMIP for chlorpyrifos analyte.•HVSMIP was applied to detect trace chlorpyrifos in spiked apple and carrot samples.
