“…The polymers having aromatic systems incorporated in main chain exhibit high stability, relatively long π bonds conjugation extent, and low energy band gap. In this group of conducting polymers, one can mention: poly( p ‐phenylene) (PPP), poly( p ‐phenylene vinylene) (PPV), poly( p ‐phenylene ethynylene) (PPE), polypyrrole (PPy), polyaniline (PANI), and polyfluorene (PF) . One of the best known group of conductive polymers is represented by polythiophene (PTh) and its derivatives .…”

The article presents the data concerning the synthesis of polythiophene (PTh) nanoparticles in aqueous medium applying emulsion polymerization. The synthetic method was studied in variety of combinations of initiator and surfactant. It was found that application of potassium peroxydisulfate (KPS) as initiator and sodium dodecyl sulfate (SDS) as the surfactant gives the best product yields. The structure, morphology, and physicochemical properties have been analyzed showing that the resulting latex have conducting film forming properties. Resulting polymers were characterized via fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), thermogravimetry-differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), and electrochemical methods [e.g. current-voltage characteristics (I-V), activation energy of electric conductivity, and doping processes]. A mechanism of the polymerization reaction is also discussed.

“…On the other hand, a kind of redox polymer has gradually been attractive for material scientists. Redox polymer was defined by IUPAC as a polymer‐containing group that can be reversibly reduced or oxidized . Reversible redox reaction can take place in the polymer main chain, as in the case of conducting polymers such as polyaniline (PANI), or in side groups, as in the case of a polymer carrying ferrocene side groups .…”

“…Reversible redox reaction can take place in the polymer main chain, as in the case of conducting polymers such as polyaniline (PANI), or in side groups, as in the case of a polymer carrying ferrocene side groups . Sensors and biosensors have been historically one of the most popular applications of redox polymers . As the main component of biosensor materials, these redox polymers essentially function as bioactive species‐binding support and polymeric electron‐transfer mediator.…”

In this article, a redox-responsive poly(ionic liquid) (redox-PIL) hydrogel Poly(1-vinyl-3-propionate imidazole phenothiazine sulfonic acid)-chitosan [Poly(VPI + PTZ-(CH 2 ) 3 SO 3 − )-CS] was produced by using chitosan (CS) crosslinking with redox-PIL Poly(1-vinyl-3-propionate imidazole phenothiazine sulfonic acid [Poly(VPI + PTZ-(CH 2 ) 3 SO 3 − )]. The incorporation of redox-active counter anions 3-(phenothiazine-10-yl) propane 1-sulfonic acid anions (PTZ-(CH 2 ) 3 SO 3 − ) into cationic PIL-polyimidazole rendered Poly(VPI + PTZ-(CH 2 ) 3 SO 3 − ) with electron catalytic ability, ionic conductivity, and electron conductivity. Poly(VPI + PTZ-(CH 2 ) 3 SO 3 − )-CS combines the properties of hydrogel and redox-PIL, thus offering intrinsic porous conducting frameworks and promoting the transport of charges, ions, and molecules, leading hydrogel with excellent electrochemical properties. The crosslinking occurrence of Poly(VPI + PTZ-(CH 2 ) 3 SO 3 − ) and CS resulting from the synthetic process of hydrogel was verified by differential scanning calorimetry and thermogravimetric analysis. A three-dimensional polymer network hydrogel with good biocompatibility and permeability was formed after crosslinking. In addition, only 64% weight loss within 600 C was observed in Poly(VPI + PTZ-(CH 2 ) 3 SO 3 − )-CS representing its thermally stable performance. When used as an electrochemical sensor, the hydrogel-modified gold electrode improved the electrocatalytic oxidation of cysteine. Differential pulse voltammetry results indicated that the detection range was from 5 × 10 −8 to 5 × 10 −3 M and the limit of detection was 6.64 × 10 −8 M.

A novel DNA probe based on caffeic acid modified disposable pencil graphite electrodes were developed for the first time for the electrochemical determination of breast cancer gene sequence (BRCA) hybridization. Amino‐linked BRCA probe highly immobilized onto the caffeic acid modified electrode by means of the interaction between the amino group of BRCA probe and the carboxyl group of caffeic acid compared to the bare electrode. 44 % signal enhancement in guanine oxidation signal was measured by caffeic acid modified electrode. Besides, these probes exhibited high selectivity towards its complementary DNA sequences (target). Hybridization between probe and target (BRCA1) was studied to evaluate the selectivity of the probes for complementary, non‐complementary and mismatch sequences. The selectivity was also tested in the presence of mixture containing the target and one base mismatch BRCA sequences in the same ratio (1 : 1). It can be said this probe can select its complementary from the mixture.
