Biochemical oxygen demand (BOD) is an important index for the assessment of organic water pollution, which needs to be detected rapidly and sensitively. In this paper, a BOD biosensor has been developed based on the direct immobilization of microorganisms around carboxyl graphene (GN-COOH) modified ultramicroelectrode array (UMEA). UMEA is designed in ring shape and hexagon distribution, which shows...
A Dual-gate graphene field effect transistor was fabricated with HfO2 and SiO2 as the back and top dielectric layers on silicon substrate, respectively. The CVD grown graphene was transferred a process by spin-coating a PMMA layer. The electrical properties of the graphene transistors were investigated. Ambipolar behavior of field effect transistor is demonstrated with the carrier mobility of the...
