“…The LOD of H2O2 is given in Table 1. It can be seen from Table 1 that the LODs obtained from different techniques are quite comparable with each other, and are much lower than the already reported data [34][35][36][37]. It can be concluded from these results that electrodeposited PACHA and PANI on the surface of an Au electrode enables the detection of H2O2 at a low concentration level.…”

Polymer-coated electrodes are widely used for the detection and oxidation of hydrogen peroxide (H 2 O 2 ). Conducting polyaniline (PANI), poly (2-hydroxyanilne) (PHA), and their copolymer poly(aniline-co-2-hydroxyaniline) (PACHA) were electrochemically synthesized on a gold substrate for H 2 O 2 detection and analysis. Cyclic voltammetry (CV), square wave voltammetry (SWV), and differential pulse voltammetry (DPV) techniques were used for electroanalysis. Both PACHA and PANI greatly reduced the gold overpotential for H 2 O 2 oxidation with enhanced current densities. The PACHA-and PANI-coated electrodes showed oxidative peaks at 0.30 and 0.50 V, respectively, in the presence of 1.4 × 10 −6 M H 2 O 2 , while PHA-coated electrodes exhibited no response. The fabricated electrodes displayed a linear response towards H 2 O 2 in range of 2 × 10 −7 to 1.4 × 10 −6 M, with very low detection limits (LODs) of 1 × 10 −7 M (for PACHA) and 1.15 × 10 −7 M (for PANI) evaluated from CV data. In case of SWV and DPV, the LODs were found to be 1.78 × 10 −7 M (for PACHA) and 1 × 10 −7 M (for PANI), respectively. The materials exhibit high sensitivity of 650 A/Mcm 2 and show good stability. The PACHA-coated electrode shows better capacitance (1.84 × 10 −3 F) than PHA-(2.52 × 10 −4 F) and PANI-coated (1.17 × 10 −3 F) electrodes.

The development of flexible sensors could enable significant advances in clinical diagnosis, defense, and environmental monitoring. Flexible glass provides the flexibility and possesses stable chemical and physical properties. Here, we show that carbon graphite and silver/silver chloride inks can be printed onto flexible glass to construct amperometric sensors, and the sensors show sensitive and rapid detections of hydrogen peroxide. We anticipate that these results could provide exciting avenues for fundamental studies of flexible electronics and flexible bioelectronics, as well as a variety of applications in fields ranging from medical diagnosis to defense.

A comparison of the analytical characteristics of two tyramine biosensors, based on graphene oxide (GRO) and polyvinylferrocene (PVF) modified screen‐printed carbon electrodes (SPCE), is reported. Diamine oxidase (DAOx) or monoamine oxidase (MAOx) was immobilized onto the PVF/GRO modified SPCE to fabricate the biosensors. Surface characteristics and electrochemical behaviour of the modified SPCEs were investigated by atomic force microscopy (AFM), scanning electron microscopy (SEM), energy dispersive X‐ray spectroscopy (EDX) and cyclic voltammetry (CV). Electrode surface composition and experimental variables such as pH and working potential were optimized in order to ensure a high performance. Under optimum experimental conditions, both DAOx/PVF/GRO/SPCE and MAOx/PVF/GRO/SPCE biosensors exhibited wide linear dynamic ranges for tyramine from 9.9×10−7 to 1.2×10−4 M and from 9.9×10−7 to 1.1×10−4 M, respectively. MAOx/PVF/GRO/SPCE biosensor showed higher sensitivity (11.98 μA mM−1) for tyramine determination than the DAOx/PVF/GRO/SPCE biosensor (7.99 μA mM−1). The substrate specifity of the biosensors to other biogenic amines namely histamine, putrescine, spermine, spermidine, tryptamine, β‐phenylethylamine and cadaverine was also investigated. The developed biosensors were successfully used for tyramine determination in cheese sample.
