“…The incubated electrodes were used for the determination of Cu ions using DPV technique. The optimum pH value was determined to be 5.00 from this study and this result is supported by some studies [38][39][40][41][42]. At higher pH values, Cu ions cannot be detected due to the precipitation formation as hydroxide.…”

a b s t r a c tIn this research, (Z)-2-(2-(hydroxyimino)-2-(3-methyl-3-phenylcyclobutyl)ethyl)-3a,7a-dihydro-1H-isoindole-1,3(2H)-dione, HMPD molecule has been grafted to the glassy carbon (GC) electrode surface. The HMPD-modified GC electrode has been originally developed and it used for the quantitative determination of Cu(II) in flour and water samples. The modification steps have been performed using cyclic voltammetry (CV). CV, electrochemical impedance spectroscopy and scanning electron microscopy have been employed for the characterization processes. Cu(II) standard solutions changing from 1.0 × 10 -9 to 1.0 × 10 -3 M have been prepared and the corresponding peak currents have been measured. From the obtained data calibration equation has been calculated I p = -1.555C cu + 15.86 which is having a 0.9974 correlation coefficient. 10.0 mL of flour and water samples have been mixed with 10.0 mL Britton-Robinson (BR) buffer solution (pH = 5.00) and HMPD/GC sensor electrode has been kept in these mixed solutions for 90 min. Differential pulse voltammetric (DPV) technique has been applied for the measurement of the peak currents. After the application of the developed sensor electrode for Cu(II) detection in flour and water samples, Cu(II) ion concentrations have been calculated from the obtained peak current values, 1.97 and 2.46 µA. The Cu(II) ion concentrations have been calculated as 1.17 × 10 -9 and 2.41 × 10 -9 M, respectively.

“…Last, this work has focused on the use of PB as model electrochrome. However, other electrochromic materials, including conducting polymers, [49,50] which have also been used in the construction of electrochromic sensors, could also be used in the mass production of new sensors using the approach presented here to formulate related screen-printing materials. Tables Table 1. Comparison of different Prussian-blue screen-printed sensors and biosensors used in the amperometric determination of H2O2.…”

Highlights We present the production of an electrochromic screen-printable paste based on Prussian Blue. These blue electrodes display excellent spectroelectrochemical reversibility and high catalytic activity towards the reduction of H2O2.  These blue electrodes enable both the electrochemical and optical quantitative determination of hydrogen peroxide.  The reported blue electrodes are highly suitable transducers for the construction of oxidase-based biosensors.  A glucose biosensor is presented to demonstrate the spectroelectrochemical capabilities of these new electrodes. AbstractPrussian Blue (PB)-modified graphite screen-printed electrodes are increasingly being used in electrochemical biosensors. However, they do not allow the observation of the electrochromism of PB. This work presents the construction of PB-based, electrochromic screen-printed biosensors. Although electrically more resistive than their graphite counterparts, these new PBbased electrodes enable both the amperometric and colorimetric detection of hydrogen peroxide.This is the first time that this has been achieved using screen-printed electrodes, and we demonstrate it spectroelectrochemically on a glucose biosensor. The biosensor electrochemical performance equals that of previously reported PB/graphite electrodes, being able to detect down to 4 µM H2O2 and 54 µM glucose. At the same time, and in contrast to PB/graphite electrodes, the new PB-based electrodes afford the optical detection of these two analytes down to 1.2 µM and 15 µM, respectively. The dynamic ranges of the glucose biosensors obtained at the PBbased electrodes are 0.1-1 mM (amperometric) and 0.025-2.5 mM (Colorimetric), matching the physiological glucose concentration range in body fluids other than blood or serum.

“…This unique ability can be applied in various fields such as smart windows, rear‐view mirrors for automobiles, military camouflage, etc . As a typical electrochromic material, polyaniline (PANI) has been intensively studied because of its high conductivity, excellent environmental stability, fast response time, low cost, easy synthesis, and so on . But there still are some factors that affect the electrochromic performance of PANI need to be overcome .…”

In this paper, a high‐performance organic/inorganic electrochromic material was synthesized by covalent bonding of polyaniline (PANI) and graphene oxide (GO). In the presence of N,N′‐dicyclohexylcarbodiimide (DCC) as dehydrating agent, GO was functionalized by p‐phenylenediamine (PPD) through an amidation reaction. Water‐processable PANI‐GO nanocomposites were prepared by copolymerization of aniline with PPD functionalized GO in the presence of poly(styrene sulfonate) (PSS) dopant in an aqueous medium. The structures and morphologies of PANI‐GO nanocomposites were characterized by Fourier‐transform infrared (FTIR) spectra, Raman spectra, transmission electron microscope (TEM) and scanning electron microscope (SEM). The results show that covalent bonding PANI‐GO nanocomposites possess better electrochemical and electrochromic properties over that of neat PANI. With 3 wt.% GO‐PPD loading, PANI‐GO‐3% exhibits the optimal electrochemical and electrochromic properties, among which the charge‐transfer resistance (RCT) is 29.4 Ω, the optical contrast is 0.72 and coloring/bleaching time is 4.45/4.28 s. Overdose GO‐PPD leads to negative influence on the contrast and switching speed, owing to the ion blocking effect brought by its two‐dimensional nanostructure.
