“…First, the presence of the Au–Ag core–shell in the graphene/PEDOT:PSS composite could facilitate a faster electron transfer process at the electrolyte/electrode interface . Second, the synergistic effect between graphene and PEDOT:PSS as conductive materials could lower resistance at the electrolyte/electrode interface and increase the electron transfer rate as well. , Thus, the enhanced electrocatalytic activity of this metal–carbon–polymer nanocomposite due to higher electronic conductivity might be intriguing to further investigate it as electrode modifier for electrochemical sensing purposes particularly for pesticide detection.…”

Herein, a nonenzymatic detection of paraoxon-ethyl was developed by modifying a glassy carbon electrode (GCE) with gold−silver core−shell (Au−Ag) nanoparticles combined with the composite of graphene with poly(3,4-ethylenedioxythiophene)/ poly(styrenesulfonate) (PEDOT:PSS). These core−shell nanoparticles (Au−Ag) were synthesized using a seed-growth method and characterized using UV−vis spectroscopy and high-resolution transmission electron microscopy (HR-TEM) techniques. Meanwhile, the structural properties, surface morphology and topography, and electrochemical characterization of the composite of Au−Ag core−shell/graphene/PEDOT:PSS were analyzed using infrared spectroscopy, field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), and electrochemical impedance spectroscopy (EIS) techniques. Moreover, the proposed sensor for paraoxon-ethyl detection based on Au−Ag core− shell/graphene/PEDOT:PSS modified GCE demonstrates good electrochemical and electroanalytical performance when investigated with cyclic voltammetry (CV), differential pulse voltammetry (DPV), and chronoamperometry techniques. It was found that the synergistic effect between Au−Ag core−shell nanoparticles and the composite of graphene/PEDOT:PSS provides a higher conductivity and enhanced electrocatalytic activity for paraoxon-ethyl detection at an optimum pH of 7. At pH 7, the proposed sensor for paraoxon-ethyl detection shows a linear range of concentrations from 0.2 to 100 μM with a limit of detection of 10 nM and high sensitivity of 3.24 μA μM −1 cm −2 . In addition, the proposed sensor for paraoxon-ethyl confirmed good reproducibility, with the possibility of being further developed as a disposable electrode. This sensor also displayed good selectivity in the presence of several interfering species such as diazinon, carbaryl, ascorbic acid, glucose, nitrite, sodium bicarbonate, and magnesium sulfate. For practical applications, this proposed sensor was employed for the determination of paraoxon-ethyl in real samples (fruits and vegetables) and showed no significant difference from the standard spectrophotometric technique. In conclusion, this proposed sensor might have a potential to be developed as a platform of electrochemical sensors for pesticide detection.

“…The commercially available flexible electrodes named poly(3,4-ethylenedioxythiophene)/ poly(4-styrenesulfonic acid) (PEDOT/PSS) are an ideal conductive polymer. Since PE-DOT/PSS electrodes possess excellent conductivity, flexibility, high electrochemical stability, and processing simplicity [34][35][36][37][38], recent studies have developed IEAP actuators based on PEDOT/PSS electrodes via drop-casting [39], dip-casting [40,41], spin-coating [42,43], and hot-pressing methods [44,45]. However, the drop or dip casting method is susceptible to generating uneven electrode surfaces.…”

High-performance electroactive polymer actuators with large bending, fast response, and high durability have gained attention in the development of micromanipulators and multifunctional bionic soft robots. Herein, we developed high-performance electroactive soft actuators fabricated with ultrathin free-standing microfibrillated cellulose (MFC)-reinforced poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT/PSS) with multi-walled carbon nanotube (MWCNT)-doped composite electrode films and ion-exchange Nafion membranes by a hot-pressing method. The prepared PEDOT/PSS-MFC-MWCNT electrodes have good film-forming properties with a Young’s modulus of 448 MPa and an electrical conductivity of 75 S/cm. The proposed PEDOT/PSS-MFC-MWCNT/Nafion soft actuators have a sustained peak displacement of 2.1 mm and a long-term cyclic stability of 94% with no degradation over 1 h at 1.0 V, 0.1 Hz. Furthermore, we fabricated soft micro-grippers based on the actuators for mimicking actual finger actions for grasping, pointing, and counting, which introduces new possibilities for the next-generation development of micromanipulators and bionic soft robotics.

“…Poly(3,4-ethylenedioxythiophene) (PEDOT)/poly(4styrenesulfonate) (PSS) (denoted as PP) has been developed as a promising conductive polymer in recent decades owing to its high chemical and thermal stability, soness, and electrical conductivity. [22][23][24] Some researchers have adopted commercially available or doped-modied PP as an alternative electrode for preparing IEAP actuators, typically employing four preparation methods: drop-casting, [25][26][27] dip-casting, 28,29 spin-coating, [30][31][32][33] and hot-pressing. 7 However, the dip/drop-casting method causes differences in evaporation rates on the substrate or concentration uctuations, readily inducing uneven electrode surfaces.…”
