“…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.

“…where the K D 0 = K D /C, in this case the C is the concentration of FLV; Therefore, the K D 0 is the value, which is calculated for standard reference concentration of 1 M [52,53]. It was found that ∆G= −0.252 and −0.272 kJ/mol for FLV/MIP complex formation for both high affinity and low-affinity binding sites of MIP, respectively.…”

A simple, efficient and reliable analytical method was developed and used for the determination of the fluvoxamine drug (FLV) in pharmaceutical preparations and biological fluids. The method is based on the cost-effective screen-printed platform for the potential transduction of the drug. Host-tailored molecular imprinting polymer (MIP) was integrated with the potentiometric platform as a recognition receptor, in which FLV, acrylamide (AAm), ethylene glycol dimethacrylate (EGDMA) and acetonitrile were used as a template, functional monomer, cross-linker, and solvent, respectively. MIP particles were dispersed in plasticized poly (vinyl chloride) (PVC) and the membrane was drop-casted on carbon screen-printed electrode. The MIP, in addition to non-imprinted polymers (NIP), was characterized and the binding experiment revealed high affinity and adsorption capacity of MIP towards FLV. The proposed sensor displayed near-Nernstian cationic slope of 55.0 ± 0.8 mV/decade (r 2 = 0.999) with a low detection limit of 4.8 × 10 −6 mol/L over a wide pH range (3.0-8.5). The electrochemical features of the proposed sensors including electrochemical impedance spectroscopy (EIS) and chronopotentiometry measurements (CP) in the presence of multi-walled carbon nanotubes (MWCNTs) as a solid contact transducer were also investigated. The applications of the proposed sensor for the determination of FLV in different dosage forms with recovery values (98.8%-101.9%) and (97.4%-101.1%), respectively compared with the reference HPLC method with acceptedFandt-student tests values at the 95% confidence level.

“…This feature is particularly suitable for the coating of several kinds of electrodes from macroelectrodes to microelectrodes. Recently, Ramanavicius et al proved that ICPs can be used for organic molecules recognition [20,21]. Specially, imprinted polypyrrole has been the most popular material in sensing application among the other ICPs for the inorganic anion recognition [11].…”

During the reversible electrochemical reactions of the intrinsically conducting polymer (ICP) films, ions are inserted in them to balance the inner charge site of the polymer. For this reason, doped ICP films with anions or cations can be good candidates for the electrochemical removal of contaminant ions from wastewater. In this work, a polymer of a phenothiazine derivative (poly(Azure A or PAA)) was electrosynthesized by cyclic voltammetry in aqueous solutions using nitrate ions as a structural template. After that, PAA film was repeatedly cycled in identical conditions in a monomer-free solution. The electrochemical anion recognition of the nitrate-imprinted poly(Azure A) (NO 3 −-PAA) was evaluated by the combination of electrochemical and mass impedance spectroscopy, the so called ac-electrogravimetry method. Ac-electrogravimetry allows the selectivity of NO 3 −-PAA to be quantified. NO 3 −-PAA exhibited a special sensitivity and selectivity for the nitrate ions over the interfering chloride ions in mixed NO 3 − and Cl − containing solutions. The Dixon plots of the kinetic constants obtained by acelectrogravimetry were used as a graphical method to reveal that NO 3 − and Cl − transfers are non-competitive at lower doped states of the polymer but competitive at higher doped states. The reversibility of nitrate incorporation controlled by an external potential modulation, the relative low cost and easy synthesis render the NO 3 −-PAA film suitable in practical implications such as nitrate scavenger in aqueous contaminated environments.
