The large amount of synthetic chemicals being released in the environment requires the development of new analytical techniques. Molecular imprinting represents an opportunity to detect such complex analytes in water. An imprinted polymer was prepared by precipitation polymerization in acetonitrile. The resulting nanoparticles were then ultrafiltered and stabilized in an aqueous solution. Studying the adsorption isotherm allowed the determination of the polymer imprinting capacities (binding constant and number of sites). Also, we found that the latex could be analyzed directly by High Performance Liquid Chromatography which would allow determining template concentration in water samples rather quickly. In addition, the nanoparticles were coated on a quartz crystal with a quartz crystal microbalance. The frequency shift recorded by the instrument being proportional to the mass adsorbed by the polymer, amounts of contaminants in water sample can be quantified.
