“…In addition, instead of enzyme based biosensors, many sensors without use of enzymes have been intensively developed for detection of disease-related target analytes (Sridhar and Park, 2018;Wang S. et al, 2020). They are constructed with electrocatalytic materials such as nanometals (Lee et al, 2018;Liu et al, 2019;Chinnadayyala et al, 2021), metal nano-oxides (Zhou et al, 2020;Dong et al, 2021), and nanocomposites Ramachandran et al, 2019;Wang S. et al, 2020). Such materials offer higher environmental stability (Lee et al, 2018;Ramachandran et al, 2019;Wang S. et al, 2020;Zhou et al, 2020), giving the stable detection performances.…”

A Redox Cu(II)-Graphene Oxide Modified Screen Printed Carbon Electrode as a Cost-Effective and Versatile Sensing Platform for Electrochemical Label-Free Immunosensor and Non-enzymatic Glucose Sensor

A novel copper (II) ions [Cu(II)]-graphene oxide (GO) nanocomplex-modified screen-printed carbon electrode (SPCE) is successfully developed as a versatile electrochemical platform for construction of sensors without an additionally external redox probe. A simple strategy to prepare the redox GO-modified SPCE is described. Such redox GO based on adsorbed Cu(II) is prepared by incubation of GO-modified SPCE in the Cu(II) solution. This work demonstrates the fabrications of two kinds of electrochemical sensors, i.e., a new label-free electrochemical immunosensor and non-enzymatic sensor for detections of immunoglobulin G (IgG) and glucose, respectively. Our immunosensor based on square-wave voltammetry (SWV) of the redox GO-modified electrode shows the linearity in a dynamic range of 1.0–500 pg.mL−1 with a limit of detection (LOD) of 0.20 pg.mL−1 for the detection of IgG while non-enzymatic sensor reveals two dynamic ranges of 0.10–1.00 mM (sensitivity = 36.31 μA.mM−1.cm−2) and 1.00–12.50 mM (sensitivity = 3.85 μA.mM−1.cm−2) with a LOD value of 0.12 mM. The novel redox Cu(II)-GO composite electrode is a promising candidate for clinical research and diagnosis.

The development of polymer-based devices has attracted much attention due to their miniaturization, flexibility, lightweight and sustainable power sources with high efficiency in the field of wearable/portable electronics, and energy system. In this work, we proposed a polyvinylidene fluoride (PVDF)-based composite matrix for both energy harvesting and energy storage applications. The physicochemical characterizations, such as X-ray diffraction, laser Raman, and field-emission scanning electron microscopy (FE-SEM) analyses, were performed for the electrospun PVDF/sodium niobate and PVDF/reduced graphene oxide composite film. The electrospun PVDF/sodium niobate nanofibrous mat has been utilized for the energy harvester which shows an open circuit voltage of 40 V (peak to peak) at an applied compressive force of 40 N. The PVDF/reduced graphene oxide composite film acts as the electrode for the symmetric supercapacitor (SSC) device fabrication and investigated for their supercapacitive properties. Finally, the self-charging system has been assembled using PVDF/sodium niobate (energy harvester), and PVDF/reduced graphene oxide SSC (energy storage) and the self-charging capability is investigated. The proposed self-charging system can create a pathway for the all-polymer based composite high-performance self-charging system.

A well-designed sandwich-like structure based on Cu2O nanocubes sandwiched between graphene oxide (GO) buffer layer was fabricated on indium tin oxide (ITO)/glass substrate via drop-casting method. The sandwich-like morphologies, GO/Cu2O/GO/ITO structures, were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) measurements. Electrochemical studies demonstrated the fact that GO/Cu2O/GO/ITO electrode revealed the superior electro-catalytic activity and electrical conductivity as a result of the introduction of graphene oxide and formation of sandwich-like structures, which effectively improved the electrical performances of Cu2O-based sandwich structure in H2O2 detection. The proposed sandwich-like GO/Cu2O/GO/ITO sensor was experimentally optimized and displayed a widespread linear response in the range from 0.25 μM to 20 mM with a low limit of detection (LOD) of 0.2 μM (S/N=3) in H2O2 sensing. Besides achieving acceptable selectivity, excellent reproducibility, and long-term stability of sandwich-like lamellar structures, GO/Cu2O/GO/ITO sensor exhibited high performance in detecting H2O2 released from A549 cells. Therefore, the novel sandwich-like GO/Cu2O/GO/ITO sensor provides an economical, potent and high-throughput platform for detecting various species involving H2O2-generation reactions for biomedical applications.
