Centimeter-long and large-scale micropatterns of reduced graphene oxide films : fabrication and sensing applications
Recently, the field-effect transistors (FETs) with graphene as the conducting channels have been used as a promising chemical and biological sensors. However, the lack of low cost and reliable and large-scale preparation ...
Label-free, electrochemical detection of methicillin-resistant staphylococcus aureus DNA with reduced graphene oxide-modified electrodes
Reduced graphene oxide (rGO)-modified glassy carbon electrode is used to detect the methicillinresistant Staphylococcus aureus (MRSA) DNA by using electrochemical impedance spectroscopy. Our experiments confirm that ssDNA, ...
Comparative studies on single-layer reduced graphene oxide films obtained by electrochemical reduction and hydrazine vapor reduction
The comparison between two kinds of single-layer reduced graphene oxide (rGO) sheets, obtained by reduction of graphene oxide (GO) with the electrochemical method and hydrazine vapor reduction, referred to as E-rGO and ...
Transparent, flexible, all-reduced graphene oxide thin film transistors
Owing to their unique thickness-dependent electronic properties, together with perfect flexibility and transparency, graphene and its relatives make fantastic material for use in both active channel and electrodes in various ...
High-density metallic nanogaps fabricated on solid substrates used for surface enhanced Raman scattering
The Raman signal of adsorbed molecules can be significantly enhanced by utilizing metallic structures with high-density Raman hot spots used as surface enhanced Raman scattering (SERS) substrates. In this work, we develop ...
Real-time DNA detection using Pt nanoparticle-decorated reduced graphene oxide field-effect transistors
A large-area, continuous, few-layer reduced graphene oxide (rGO) thin film has been fabricated on a Si/SiO2 wafer using the Langmuir–Blodgett (LB) method followed by thermal reduction. After photochemical reduction of Pt ...
