In neural tissue engineering , biomaterial scaffolds that have high conductivity and customized structures are crucial in promoting nerve regeneration. Poly(3,4-ethylenedioxythiophene) (PEDOT) has emerged as a promising conductive polymer with excellent chemical stability and biocompatibility. However, traditional three-dimensional (3D) printing of PEDOT-based conductive scaffolds faces challenges in limited printing resolution, poor solubility, and brittleness of conductive materials . Herein, digital light processing (DLP) printing was used to fabricate complex hydrogel structures using gelatin methacryloyl (GelMA) and chitosan (CS) while incorporating PEDOT nanoparticles through interfacial polymerization to create conducting pathways within a hydrogel structure. The integration of PEDOT significantly enhanced the electrical conductivity and mechanical properties of the GelMA/CS hydrogel while preserving printed details. The GelMA/CS-PEDOT hydrogel promoted cell proliferation and facilitated axon outgrowth of PC12 cells and Schwann cells during in vitro culture. Moreover, in vitro direct current electrical stimulation promoted axon elongation of PC12 cells cultured on a conductive substrate. In vivo studies used a conductive nerve conduit to repair a 10-mm rat sciatic nerve defect, validating the efficacy of GelMA/CS-PEDOT scaffold in peripheral nerve injury repair. These findings highlight the significant potential of conductive GelMA/CS-PEDOT hydrogel in the field of neural tissue engineering.

A highly-sensitive electrochemical sensor based on single walled carbon nanotubes (SWCNTs) nanocomposite electro-catalyst supported molecularly imprinted poly(3,4-ethylenedioxythiophene) (PEDOT) film modified with two-dimensional layered tungsten sulfide (WS 2 ) nanosheet for the detection of vitamin B 2 (VB 2 ) was successfully developed. Molecularly imprinted WS 2 -PEDOT film was prepared by the electrochemical co -polymerization of functional monomer 3,4-ethylenedioxythiophene in the presence of template molecule VB 2 and WS 2 nanosheet. SWCNTs nanocomposite modified electrode was obtained by drop-coating SWCNTs dispersion containing graphene oxide (GO) onto GCE surface. WS 2 was used for improving the denseness and smoothness in the morphology and structure of PEDOT. GO was employed for enhancing the electro-catalytic capacity of SWCNTs and the interaction with template molecule via functional groups. The imprinted sensor was characterized, and its performance and parameters were investigated and optimized using linear sweep voltammetry. Under optimized conditions, the prepared imprinted sensor displayed a good linear response to VB 2 in wide concentration ranges from 0.002 to 0.9 μM with a low detection limit of 0.7 nM, and successfully applied to electrochemically detect VB 2 in drug samples with good reproducibility, repeatability and storage stability. The new design for the facile fabrication of mimic electrode will open up a new horizon in the development of highly-sensitive biomimic/imprinted sensors.

To enhance the sensitivity of an aptasensor, a novel strategy was designed to develop an electrochemical aptasensor based on poly(3,4-ethylenedioxy thiophene)–gold nanoflower (PEDOT–AuNF) composites supported on a three-dimensional graphene oxide sponge (GOS). GOS with a three-dimensional sponge-like porous structure, exhibiting excellent electrical conductivity and a large surface area, provided the first amplification of the electrochemical signal for ochratoxin A (OTA) detection. PEDOT–AuNFs, synthesized by an ionic liquid-assisted one-pot method, presented a peculiar hierarchical flower-like structure, a high electroactive surface area, and more binding sites for immobilizing the aptamer molecules by the Au–S bonds. When PEDOT–AuNFs were supported on the surface of GOS by the interaction of the π–π packing between PEDOT and graphene oxide, a synergistic effect was produced to provide the second amplification for the aptasensor. PEDOT–AuNFs/GOS provided an ultrasensitive detection technique by multiple signal amplification for the electrochemical sensing of OTA. Consequently, this strategy not only endowed the aptasensor with high sensitivity but also needed no complicated signal amplification. The electrochemical sensor was fabricated successfully on a glassy carbon electrode to detect OTA with a linear response in the range of 0.01–20 ng L−1 and a limit of detection of 4.9 pg L−1. Moreover, it displayed good specificity, reproducibility and stability. The utilization of the proposed aptasensor for the quantitative determination of OTA in wine indicates that it can find promising applications in detecting OTA and even other mycotoxins in foodstuffs.

Transparent poly (3,4-ethylenedioxythiophene) (PEDOT) film is electrochemically polymerized on conducting substrate as counter electrode (CE) for bifacial dye sensitized solar cells application. In order to further boost the catalyst property of PEDOT, Pt films with optimized precursor loading is studied. The addition of Pt nanoclusters not only improves the coverage of the PEDOT film, but also greatly enhances conductivity and electrocatalytic property of the Pt/PEDOT composite film. The DSSC fabricated by the Pt-10/PEDOT CE gains 6.77 % PCE under the front-illumination, which is the highest among all the other CEs of the pristine Pt and pristine PEDOT. For the back-illumination, a decent PCE of 4.63 % is achieved by the composite Pt-10/PEDOT CE. The result herein demonstrates that Pt-10/PEDOT composite CE is a cost effective alternative to traditional Pt CE. Its good transmittance makes it suitable for bifacial DSSCs in building integrated photovoltaics (BIPVs).

Negatively charged carboxylated nanocrystalline cellulose (CNCC) and positively charged poly(diallyldimethyl ammonium chloride) (PDDA) were alternatingly assembled on the surface of a glassy carbon electrode to form a relatively uniform polyelectrolyte multilayer nanocomposite (CNCC/PDDA) n . It was then incorporated into a matrix of conducting poly(3,4-ethylenedioxythiophene) (PEDOT) electrodeposited on the surface of the electrode. The nanocomposites were prepared in various ratios of PEDOT and (CNCC/PDDA), and then characterized by transmission electron microscopy, scanning electron microscopy, electrochemical impedance spectroscopy, cyclic voltammetry, and differential pulse voltammetry. The PEDOT/(CNCC/PDDA) 4 nanocomposite showed the lowest electrochemical impedance and best electrocatalytic activity towards the oxidation of nitrite. Based on these findings, an amperometric sensor was developed which, if operated at 0.80 V (vs. SCE), can detect nitrite in the 0.2 μM to 1.73 mM concentration range with a 57 nM detection limit.

The novel nanocomposite of Ni(OH) 2 nanoparticles over reduced graphene oxide and poly (3,4-ethylenedioxythiophene) hybrid film (Ni(OH) 2 @PEDOT-rGO) have been successfully fabricated via a facile, scalable and easy-to-control electrodeposition method. The characterization results of scanning electron microscope (SEM) and electrochemical techniques show that Ni(OH) 2 nanoparticles with an average particle size about 10 nm are uniformly deposited on PEDOT-rGO hybrid film with rough surface and reveal outstanding performance for detecting glucose. The enzyme-free glucose sensor exhibits an ultrafast response time (< 1 s), a wide linear range (0.002–7.1 mM), a low detection limit (0.6 μM) and a high sensitivity (346 μA mM −1 cm −2 ). Moreover, the sensor also displays superb selectivity, excellent reproducibility and good stability. The outstanding properties of the sensor may be attributed to the synergistic effect of Ni(OH) 2 nanoparticles possessing high electro-catalysis activity and PEDOT-rGO having well conductivity. More importantly, the sensor was successfully used to determine glucose in the real samples. In addition, the mechanism of electrodeposited PEDOT-rGO and glucose oxidase was investigated.

Conductive hydrogels have garnered substantial research attention owing to their exceptional flexibility, remarkable stretchability, and superior electrical conductivity. In this study, polyacrylamide/carboxymethyl cellulose sodium (PAM/CMC) double-network hydrogels were synthesized via a one-pot method, followed by in situ surface polymerization of the conductive polymer poly(3,4-ethylenedioxythiophene) (PEDOT) on the hydrogel surface. Additionally, the freeze-resistance and moisture-retention properties of the hydrogel were enhanced through glycerol immersion, leading to the development of a PAM/CMC/PEDOT/Glycerol (MCPG) composite hydrogel with enhanced conductive performance. The MCPG composite conductive hydrogel exhibits outstanding mechanical properties, including an extraordinary tensile strain capacity (1750 %), excellent anti-freezing performance (maintaining flexibility at − 20 °C), and superior moisture retention capability. The strain sensor fabricated using MCPG hydrogel demonstrates an ultra-wide detection range (0–500 %), high sensitivity (GF = 5.65), and rapid response/recovery characteristics (300 ms), enabling comprehensive monitoring of various human joint movements. Furthermore, the triboelectric nanogenerator assembled with MCPG hydrogel (MCPG-TENG) exhibits exceptional electrical output performance, achieving an open-circuit voltage of approximately 118 V. This device is capable of powering small electronic devices and enabling information transmission. Consequently, the high-performance flexible sensors and TENGs developed in this study, based on the self-assembly of PEDOT on the hydrogel surface and leveraging their superior stretchability and stable conductive properties, hold broad application potential in the fields of intelligent human–machine interfaces and wearable electronic devices.

Conductive hydrogels have emerged as essential components in wearable electronics due to their intrinsic flexibility, stretchability, and electrical conductivity. However, the simultaneous realization of mechanical robustness, continuous conductive networks, strong adhesion, frost resistance, and structural tunability remains a formidable challenge. Herein, we fabricated a sulfated cellulose (SC) with a high degree of substitution, which acts as a green stabilizer and reactive template to induce the in-situ oxidative polymerization of 3,4-ethylenedioxythiophene (EDOT) and formed PEDOT: SC dispersions. The resulting PEDOT:SC dispersions exhibit remarkable colloidal stability, high electrical conductivity (1.75 S/cm), and freeze-dry re-dispersibility without performance loss. Based on this stable dispersion, we developed multifunctional hydrogels through copolymerization with acrylamide and doping with lithium chloride. The resulting hydrogels exhibit exceptional stretchability (650 %), high conductivity (52.4 mS/cm), strong adhesion, and robust anti-freezing performance. Notably, the hydrogels maintain mechanical integrity and sensing accuracy at −20 °C, supporting stable motion detection and Morse code signal transmission under frozen conditions. This work demonstrates a green and efficient strategy for constructing high-performance conductive hydrogels and dispersions, offering significant potential for wearable electronics in extreme environments.

In this paper, Bismuth/poly(3,4-ethylenedioxythiophene) (Bi/PEDOT) modified electrochemical modified electrodes were prepared by electrochemical deposition method, and the electrochemical performance of the electrode was investigated using cyclic voltammetry under the optimal experimental conditions. The PEDOT polymer has high conductivity, and bismuth can form an alloy with cadmium ions. Bi/PEDOT nanocomposite materials have a larger specific surface area and more active sites, which is more conducive to absorbing more cadmium ions (Cd 2+ ). The Differential pulse anodic stripping voltammetry method was used to study the electroanalytical performance of the sensor for Cd 2+ . The data show that the oxidation peak current of cadmium ions in the Bi/PEDOT modified electrode is significantly higher than that of other electrodes, due to the synergistic effect of the composite conductive materials. In the concentration range of 1 nM-40 μM, the concentration of cadmium ions shows a good linear relationship with the peak current, and the lowest detection limit is 0.33 nM. In addition, the sensor also exhibits good stability, reproducibility and very low detection limit, which can be used for rapid determination of trace cadmium ions, with a recovery rate in actual sample analysis of 101.4 %-104.0 %.

Exploiting high-efficiency and durable electrocatalysts toward the methanol oxidation reaction (MOR) is crucial for the advancement of direct methanol fuel cells (DMFCs). Herein, we demonstrate the loading of platinum–palladium bimetallic nanoparticles (Pt–Pd NPs) onto poly(3,4-ethylenedioxythiophene) (PEDOT)-embellished titanium carbide (Ti3C2Tx) nanosheets as the electrocatalyst (Ti3C2Tx/PEDOT/Pt–Pd) via a facile and rapid chemical reduction-assisted one-pot hydrothermal process. The structural and morphological analyses of Ti3C2Tx/PEDOT/Pt–Pd indicate that the three-dimensional (3D) hybrid structure formed between PEDOT and Ti3C2Tx provides a sizable active surface and more active sites, which enhances the homogeneous dispersion of the Pt–Pd NPs and facilitates mass transfer. The Schottky junctions formed between PEDOT and Pt–Pd NPs contribute to charge transfer. The electronic effects and synergistic interactions between the support and catalyst favor the electrocatalytic activity of the catalyst. The electrochemical test results reveal that the Ti3C2Tx/PEDOT/Pt–Pd catalyst has prominent electrocatalytic capability for the MOR. Compared with Ti3C2Tx/Pt–Pd and commercial Pt/C catalysts, the Ti3C2Tx/PEDOT/Pt–Pd catalyst has a larger electrochemical activity surface area (ECSA = 122 m2 g−1) and higher mass activity (MA = 1445.4 mA mg−1), as well as better CO tolerance and more reliable long-term durability (a peak current density retention of 71% after 5200 s).

With the miniaturization of integrated circuits driving increased demand for high-frequency alternating current (AC)-line filtering capacitors, portable electrochemical capacitors (ECs) must reconcile two persistent challenges: i) the inherent contradiction in synergistic enhancement between areal capacitance ( C A ) and volumetric capacitance ( C V ) at the condition of high frequency response, and ii) developing scalable fabrication methods. To address these issues, an electrostatic-induced Marangoni assembly process is introduced, which enables large-area, rapid deposition of poly(3,4-ethylenedioxythiophene) (PEDOT) films with a uniform, 3D fibrous porous network. By pre-treating the PEDOT:poly(styrenesulfonate) (PSS) ink with a polar solvent and applying an electrostatic field, Marangoni flows align microdroplets into a continuously interconnected 3D architecture. This structure not only facilitates ultrafast ion transport but also provides abundant storage sites, yielding a sultaneous enhancement in C A (1.72 mF cm⁻ 2 ) and C V (13.2 F cm⁻ 3 ), as well as an exceptional phase angle of −82.9° at 120 Hz. These metrics surpass those of most reported carbon- and PEDOT-based filtering capacitors. Moreover, the method accommodates high-loading of pseudocapacitive materials, demonstrating its versatility for composite electrode engineering. Subsequent AC-line filtering tests confirm the practical applicability of these electrodes, offering a scalable route to miniaturized capacitors with synergistically optimized C A and C V .
