MoS2 nanosheet functionalized with Cu nanoparticles and its application for glucose detection

A highly sensitive enzymeless glucose sensor based on 3D graphene–Cu hybrid electrodes

“…Several studies have shown that the Cu nano-layer along with 2D materials are capable of catalyzing glucose oxidation, and it has the capacity to direct the electrochemical detection of glucose without any enzymes or other mediators. [37][38][39] Fig. 6 Electrochemical measurements were performed in the 75mM NaOH electrolyte solution containing 2 mM glucose: (a) CV responses for Cu/3D graphene/NF, 3D graphene/NF and Ni foam electrodes measured at a scan rate of 50 mV/s; (b) CV for Cu/3D graphene/NF hybrid electrode measured at different scan rates; (c) I p versus potential (V) for Cu/3D graphene/NF electrode.…”

Synthesis and enhanced microwave absorption properties of PVB/Co 2 Z/RGO layered composite

“…And the plot of ε′ versus ε″ would be a single semicircle, which is usually denoted as the Cole-Cole semicircle, and each semicircle corresponds to one Debye relaxation process 44 . As shown in Figure 7b, four semicircles can be found in the as-synthesized PVB/Co 2 Z/RGO composite, corresponding to their relative complex permittivity and dielectric loss tangent.…”

“…Compared with those of PVB/Co 2 Z composite ( ε′= 6.8-15.1, ε″= 0-1.7 ), the ε″ value for the PVB/Co 2 Z/RGO composite exhibits a strong peak in the 12~18 GHz range, indicating a resonance behavior, which is due to the fact that for the PVB/Co 2 Z/RGO composite the interface effect becomes significant43 . In addition, RGO also possesses the chemically active surfaces, coupled with native defects and metallic character44 . The variation of the complex permeability spectra in the range of 2-18 GHz is shown inFigure 6c-d.…”

Preparation of MoS2‐graphene Hybrid Nanosheets and Simultaneously Electrochemical Determination of Levodopa and Uric Acid

“…Recently, MoS 2 nanoflakes, a 2D layer structure analogous of graphene, have been recognized as promising candidates for application in electronics and catalysis . The abundant exposed edges make MoS 2 nanoflakes show the superior biosensing performance when detecting biomolecules . The MoS 2 nanoflakes have been widely explored as the electrode materials of electrochemical biosensors .…”
