One novel molecular imprinting nanowires chemiluminescence sensor: preparation and pendimethalin recognition

One kind of pendimethalin-imprinted nanowires has been synthesized using nanoporous alumina membrane as the template. Because of the large surface-to-volume ratio of nanowires structure, the effective binding sites at the surface of the nanowires were sharply increased, and the recognition capability for template molecules was greatly improved. Taking the pendimethalin-imprinted nanowires as the recognition part, a novel chemiluminescence–molecular imprinting sensor was prepared. Its application in the detection of trace pendimethalin in foodstuff showed excellent performance of simple operation, high sensitivity, and good selectivity, through which the high throughput sample detection was realized with satisfied results.
