Label-free detection and discrimination of poly-brominated diphenylethers using molecularly imprinted photonic cross-reactive sensor arrays

Abstract

Molecularly imprinted photonic polymers can serve as ideal sensing elements for efficiently creating cross-reactive sensor arrays. Based on this concept, a new method for sensitive and label-free detection of challenging PBDEs was developed, by which the direct detection and discrimination of trace levels of PBDEs against a high-background of interferents was achieved with 100% accuracy.
