“…Nanostructured metals are attracting intensive interests from the scientific community, owing to their fabulous properties and diversity of applications [57,58]. A number of studies have explored the cooperation and synergistic effects between nanostructured metals and graphene paper, such as Pt nanoparticles (PtNPs) [59], Pt nanowires (PtNWs) [60], Au@Pt core-shell NPs [61], Au nanoparticles (AuNPs) [62] and Ag nanoparticles (NPs) [63].…”

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.

“…It indicated that glucose had no effect on CdTe QDs-CHIT/GCE. When Au NPs were conjugated onto CdTe QDs-CHIT/GCE, the ECL peak intensity was decreased to about 3421 due to the inner filter effect of Au NPs toward the electrode surface (curve c) (Zhang et al, 2012;Shota et al, 2011). Upon addition of glucose, Au NPs catalyzed glucose to produce gluconic acid (Luo et al, 2010).…”

“…Until now, many methods have been used to detect melamine; for instance, surface enhanced Raman spectroscopy (SERS) [2], colorimetric sensors [3], fluorescence sensors [4], enhanced enzyme-linked immunosorbent assays [5], and immune chromatographic strips [6]. In our previous work, we developed a magnetic relaxation switch (MRSw) assay for detecting melamine with functionalized Fe/Fe 3 O 4 nanoparticles [7].…”
