Electrical detection of metal ions using field-effect transistors based on micropatterned reduced graphene oxide films
The electrical property of graphene is highly sensitive to its local environment, which makes graphene an ideal channel material in electronic sensors. Reduced graphene oxide (rGO) has been used as the desirable alternative ...
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 ...
3D graphene foam as a monolithic and macroporous carbon electrode for electrochemical sensing
Graphene, a single-atom-thick monolayer of sp2 carbon atoms perfectly arranged in a honeycomb lattice, is an emerging sensing material because of its extraordinary properties, such as exceptionally high specific surface ...
Memory devices using a mixture of MoS2 and graphene oxide as the active layer
A mixed film consisting of 2D MoS2 and graphene oxide (GO) nanosheets is used to fabricate memory devices. The conductive MoS2 component in the MoS2-GO film increases the film conductivity, thus facilitating oxygen migration ...
Fabrication of ultralong hybrid microfibers from nanosheets of reduced graphene oxide and transition-metal dichalcogenides and their application as supercapacitors
Two-dimensional materials have attracted increasing research interest owing to their unique electronic, physical, optical, and mechanical properties. We thus developed a general strategy for the fabrication of ultralong ...
