“…The obtained value of Gibbs free energy change is in the same order as that value calculated by other authors [28] and confirmed in our previous works [27]. These values are close to that which are typical for 2-3 hydrogen bounds formation and electrostatic interactions [29,30].…”

“…Polypyrrole (Ppy), the one of conducting polymers, has been widely used for sensor applications. During the formation of Ppy layers can be modified by molecular imprints and in such way molecularly imprinted Ppy can be formed (MIP‐Ppy), which contains molecularly imprinted sites, which are complementary and selective for imprinted target molecules. The most efficient formation of MIP‐Ppy can be based on electrochemical polymerization of the pyrrole monomer in the presence of target molecules .…”

Molecularly imprinted polymers are important tools for the design of sensors and other molecular recognition based analytical systems. In this paper the development of a photoelectrochemical sensor for selective bisphenol determination is reported. The sensor is based on a glass/ZnO/MIP‐Ppy structure consisting of glass modified by a ZnO layer (glass/ZnO), which is functionalized by molecularly imprinted conducting polymer polypyrrole (MIP‐Ppy). The sensitivity of the sensor to bisphenol is in the range of 0.7–12.5 µm. Selectivity tests to other bisphenolic compounds are performed. Some aspects of a photoinduced response mechanism in glass/ZnO/MIP‐Ppy nanostructures are predicted and discussed.

“…In addition, comparison of the dissociation constants, Kds, derived from binding kinetics might shed light on binding affinity between IgG and the synthesized IgG‐MIPs . The calculated Kd values (3.1nM, 4.8nM, and 5.0nM for IgG‐MI‐PmPD, IgG‐MI‐PDA, and IgG‐MI‐PEDOT, respectively) were in consistence with the conclusions above, demonstrating somewhat higher binding affinity of IgG to IgG‐MI‐PmPD.…”

Molecular imprinting has become a promising approach for synthesis of polymeric materials having binding sites with a predetermined selectivity for a given analyte, the so-called molecularly imprinted polymers (MIPs), which can be used as artificial receptors in various application fields. Realization of binding sites in a MIP involves the formation of prepolymerization complexes between a template molecule and monomers, their subsequent polymerization, and the removal of the template. It is believed that the strength of the monomer-template interactions in the prepolymerization mixture influences directly on the quality of the binding sites in a MIP and consequently on its performance. In this study, a computational approach allowing the rational selection of an appropriate monomer for building a MIP capable of selectively rebinding macromolecular analytes has been developed. Molecular docking combined with quantum chemical calculations was used for modeling and comparing molecular interactions among a model macromolecular template, immunoglobulin G (IgG), and 1 of 3 electropolymerizable functional monomers: m-phenylenediamine (mPD), dopamine, and 3,4-ethylenedioxythiophene, as well as to predict the probable arrangement of multiple monomers around the protein. It was revealed that mPD was arranged more uniformly around IgG participating in multiple H-bond interactions with its polar residues and, therefore, could be considered as more advantageous for synthesis of a MIP for IgG recognition (IgG-MIP). These theoretical predictions were verified by the experimental results and found to be in good agreement showing higher binding affinity of the mPD-based IgG-MIP toward IgG as compared with the IgG-MIPs generated from the other 2 monomers.
