ABSTRACT : This article examines the usefulness of a conducting polymer, polypyrrole, in the design of molecularly imprinted polymer-based sensors. Basic electrochemical techniques previously described in this Journal are applied in the preparation of the molecularly imprinted conducting polymer polypyrrole (mPpy). Pulsed amperometric detection (PAD) method is applied for the estimation of success in the preparation of mPpy and for the detection of analyte interaction with the complementary cavities imprinted within the polymeric backbone. Caffeine was selected as a template molecule for molecular imprinting of polypyrrole. Estimation of caffeine concentration has an analytical impact owing to its high biological activity. Moreover, caffeine is well known to the students. Application of electrochemical polymerization techniques enables preparation of molecularly imprinted conducting polymer-based analytical systems. Such systems exhibit an artificially created affinity and can act as synthetic receptors.
