“…LOD and LOQ values thus obtained were 0.03 and 0.10 mM respectively. It is interesting to remark that this simple electrochemical biosensor design using pins as electrodes shows an LOD and linear dynamic range similar, or in some cases better, than those obtained with other glucose sensors previously developed, even those employing carbon nanomaterials or nanoparticles on glassy carbon electrodes (Su et al, 2014;Ye et al, 2015): 0.01 -0.3 mM and 0.05 -1.2 mM respectively), using a combination of a paper disk with commercial screen-printed electrodes (Chandra Sekar et al, 2014;Kong et al, 2014): LOD of 0.01 and 0.1 mM respectively), or employing screen-printed electrodes based on paper (Rungsawang et al, 2015): LOD of 0.86 mM) (Table S1). …”

This work describes the use of mass-produced stainless-steel pins as low-cost electrodes to develop simple and portable amperometric glucose biosensors. A potentiostatic three-electrode configuration device is designed using two bare pins as reference and counter electrodes, and a carbon-ink coated pin as working electrode. Conventional transparency film without any pretreatment is used to punch the pins and contain the measurement solution. The interface to the potentiostat is very simple since it is based on a commercial female connection. This electrochemical system is applied to glucose determination using a bienzymatic sensor phase (glucose oxidase/horseradish peroxidase) with ferrocyanide as electron-transfer mediator, achieving a linear range from 0.05 to 1mM. It shows analytical characteristics comparable to glucose sensors previously reported using conventional electrodes, and its application for real food samples provides good results. The easy modification of the position of the pins allows designing different configurations with possibility of performing simultaneous measurements. This is demonstrated through a specific design that includes four pin working-electrodes. Different concentrations of antibody labeled with alkaline phosphatase are immobilized on the pin-heads and after enzymatic conversion of 3-indoxylphosphate and silver nitrate, metallic silver is determined by anodic stripping voltammetry.

“…Because GO contains a notable number of oxygen-containing groups, it provides remarkable opportunities for further modification with polymer either by 'grafting to' or by 'grafting from' techniques. (2) Non-covalent attachment such as electrostatic attraction, hydrogen bonding or π-π stacking; a variety of polymers have been incorporated into graphene-based films with a uniform multilayer structure and novel functionality, such as polyaniline [87][88][89][90][91], poly(sodium 4-styrenesulfonate) [92] and poly(p-phenylene vinylene) [48]. Recently, Mu et al developed a series of PVDF-modified graphene monolayer papers with a gradient rGO/GO structure.…”

Graphene paper as a new form of graphene-supported nanomaterials has received worldwide attention since its first report in 2007. Due to their high flexibility, lightweight and good electrical conductivity, graphene papers have demonstrated the promising potential for crucial applications in electrochemical sensors and energy technologies among others. In this chapter, we present some examples to overview recent advances in the research and development of two-dimensional (2D) graphene papers as new materials for electrochemical sensors. The chapter covers the design, fabrication, functionalization and application evaluations of graphene papers. We first summarize the mainstream methods for fabrication of graphene papers/membranes, with the focus on chemical vapour deposition techniques and solution-processing assembly approaches. A large portion of this chapter is then devoted to the highlights of specific functionalization of graphene papers with polymer and nanoscale functional building blocks for electrochemical-sensing purposes. In terms of electrochemical-sensing applications, the emphasis is on enzyme-graphene and nanoparticle-graphene paper-based systems for the detection of glucose. We finally conclude this chapter with brief remarks and outlook.
