“…The presented approaches ( Table 2) need more complicated methods for immobilization of the nanocomposites, such as using Nafion immobilization over the sensor, 54 physical adsorption (usually with bad adhesion to substrates) 60 or electrodeposition. 53,[55][56][57][58][59] The sensors proposed by Lin et al 53 (carbon nanotubes), Chen et al 57 (nanowhiskers of PEDOT) and Nabid et al 60 (nanofibers of PEDOT) present a great effect of surface area, influencing the detection limit and the sensitivity. Even though, the GCE/Au/PEDOT-PDLLA sensor presents a very high sensitivity (8.36 × 10 −3 A mol −1 L cm −2 ) when compared to other sensors (Table 2), while the more sensitive needs to apply more energy for sensing (-550 mV).…”

Biocompatible electrochemical devices are challenging to develop due to the toxicity of many advanced electrode materials and the difficulty to degrade the discarded material. Few recent advances were made in the synthesis of conducting biodegradable composites of polymers for electrode materials. In this article we describe the synthesis of two new inorganic/organic nanocomposites of Au nanoparticles and conducting polymers based on the biodegradable polymer poly(D,L-lactic acid) (PDLLA): Au nanoparticles/oligomers of 3,4-ethylenedioxythiophene (EDOT)-PDLLA and Au nanoparticles with poly(3,4-ethylenedioxythiophene) (PEDOT)-PDLLA. The nanocomposites were carefully analyzed; the gold nanoparticles mean sizes were 8 ± 3 and 7 ± 2 nm, respectively. 1 H and 13 C nuclear magnetic resonance (NMR) demonstrated the polymerization of EDOT-PDLLA made through one-pot reaction with Au III precursor. Raman spectra show that PEDOT-PDLLA is formed in the synthesis of Au/PEDOT-PDLLA. The immobilization of Au/PEDOT-PDLLA on glassy carbon electrodes is easy and more stable than the immobilization of simple PEDOT. Au/PEDOT-PDLLA catalyzes the reduction of H 2 O 2(aq) , which was detected by chronoamperometry. The sensor is stable and presents sensitivity of 8.36 × 10 −3 A mol −1 L cm −2 , linear range of 1-45 mmol L −1 and limit of detection of 0.17 mmol L −1 .

“…In comparison, the sensitivity of a glucose sensor based on platinum nanoparticles and graphene oxide hydrogel was reported to be 137.4 µA•mM −1 •cm −2 [30]. Excellent electroanalytical properties were also revealed by the polypyrrole-poly(3,4-ethylenedioxytiophene)-Ag for electrochemical DNA sensing [28], PEDOT-PSS as a voltammetric sensor for the determination of caffeic acid [31] or PEDOT-Palladium particles in a voltammetric sensor for hydrogen peroxide [32].…”

In this work, a new approach for using a 3D polypyrrole (PPy) conducting polymer as a sensing material for glucose detection is proposed. Polypyrrole is electrochemically polymerized on a platinum screen-printed electrode in an aqueous solution of lithium perchlorate and pyrrole. PPy exhibits a high electroactive surface area and high electrochemical stability, which results in it having excellent electrocatalytic properties. The studies show that using the recurrent potential pulse technique results in an increase in PPy sensing stability, compared to the amperometric approach. This is due to the fact that the technique, under certain parameters, allows the PPy redox properties to be fully utilized, whilst preventing its anodic degradation. Because of this, the 3D PPy presented here has become a very good candidate as a sensing material for glucose detection, and can work without any additional dopants, mediators or enzymes.
