This critical review describes a class of polymers prepared by electrochemical polymerization that employs the concept of molecular imprinting for chemical sensing. The principal focus is on both conducting and nonconducting polymers prepared by electropolymerization of electroactive functional monomers, such as pristine and derivatized pyrrole, aminophenylboronic acid, thiophene, porphyrin, an...

A novel electrochemical sensing approach, based on electropolymerization of a molecularly imprinted polypyrrole (MIPpy) film onto a glassy carbon electrode (GCE) surface, was developed for the detection of flunixin (FXN). The sensing conditions and the performance of the constructed sensor were assessed by cyclic, differential pulse and (DPV) square wave voltammetry (SWV). The sensor exhibited ...

Organic electrochemical transistors are considered today as a key technology to interact with biological medium through their intrinsic ionic-electronic coupling. In this paper, the authors show how coupling can be finely tuned (in operando) post-microfabrication via electropolymerization technique. This strategy exploits concept of adaptive sensing where both transconductance and impedance tun...

To improve reproducibility, stability and sensitivity, a bismuth (Bi) thin film was coated on glassy carbon (GC) substrates which surfaces were modified with a porous thin layer of polyaniline (PANI) via multipulse potentiostatic electropolymerization to form Bi/PANI/GC electrodes (Bi/PANI/GCEs). The Bi/PANI/GCEs were used successfully for simultaneous detection and determination of Cd2þ and Pb...

ABSTRACT Polymeric polypyrrole and polythiophene solid phase microextraction (SPME) coatings were prepared using electropolymerization with a linear sweep voltammetry technique. Physicochemical properties were measured using different methods, in particular small angle X-ray scattering and scanning electron microscopy. By using innovative approaches for pore size measurement, we were able to ca...

The electropolymerization of 7,14-diphenylacenaphtho[1,2-k ]fluoranthene on a platinum or indium tin oxide (ITO) electrode produces an electroactive film which displays fluorescence and electrochromism. We report a study of the electrochemical properties and other characteristics of this film, such as the resistance dependence by the potential applied to the electrode. In particular, the film s...

This work deals with the development of screen-printed carbon electrodes modified with L-glutamic acid via two different approaches: electropolymerization (SPCE/PGA) and aryl diazonium electrochemical grafting (SPCE/EGA). SPCE/PGA and SPCE/EGA were analytically compared in the determination of hydrochlorothiazide (HCTZ) by differential pulse voltammetry. Both electrochemical characterization an...

Recent studies on electropolymerization methods toward one-dimensional conducting polymer structures are summarized in this review. In particular, advanced techniques for templated of aromatic monomers, which migration monomers into nanopores the template is highly enhanced by using electrophoretic effect, described. For templateless approach, electric field–driven bipolar 3,4-ethylenedioxythio...
