Investigation of the Polyaniline nanoparticles as the substrate of Molecular Imprinted Polymer

The current research work deals with investigation of the polyaniline nanoparticles as the
substrate of the molecular imprinted polymer. Molecular imprinting is an interesting way to
emulate the natural molecular identification that will be realized by preparing artificial
identification sites with preset election for different target analytes. In this method, the target
analyte acts as a template and will be connected to functional monomers through covalent or
non-covalent bonding during the process of polymerization. Among all the conducting
polymers, polyaniline is known for its unique electrical conductivity which can be controlled
by the degree of oxidation of the main chain and protonation. Also, it shows different color
changes with respect to the degree of oxidation and the surrounding pH. The results and
investigations conducted in this study suggest that molecular imprinted polymers can be
successfully developed by using aniline as monomer and preparation of linear polymer, and
by using method of conductometry, the presence or absence of imprinted substances can be
observed in the polymer according to the changes in conductivity caused by these phenomena.
