- In this paper, we present a simple and rapid method for monitoring bisphenol A (BPA) and its biodegradation in environmental water using a fluorescent molecularly imprinted polymer chemosensor (fMIPcs). A fluorescent molecularly imprinted polymer (fMIP) was first synthesized by precipitation polymerization method using BPA as template, dansyl methacrylate as functional monomer. Then a fMIPcs was constructed by combining the fMIP with a fluorescent microplate reader. The fMIPcs displayed selective, concentration-dependent fluorescence quenching in response to BPA in water even in the existence of interferences, thereby allowing reliable high through-put quantification of BPA via simple fluorescence measurements. The fMIPcs was able to directly quantify BPA (from 10 to 2000μgL(-1)) in different environmental water samples (distilled water, distilled water containing heavy metals and humic acid, tap water, and river water) with high accuracy, and to monitor BPA biodegradation in real-time. Using the fMIPcs, it was possible to achieve fast analytical results with lower limit of detection for BPA (3μgL(-1)) from smaller sample volume (250μL), which are superior to many relevant methods reported in the literature. Moreover, BPA levels and biodegradation rates measured by fMIPcs are comparable to the instrument-based method (HPLC). The fMIPcs developed in this work offers a new solution for simple, rapid, accurate and high through-put BPA quantification, and makes it possible to monitor BPA biodegradation in real time.
