Nanotechnology gave some exceptionally interesting results for detecting certain biological phenomena. New horizons for intracellular measurements has been opened due to the research regarding optical nanobiosensors with submicron- sized dimensions. The utilization of different nanomaterials such as nanoparticles, nanotubes, nanorods and nanowires had empowered faster detection and increased reproducibility. Exploiting the remarkable properties of the nanomaterials, faster and more sensitive nanobiosensors are able to be produced. The novel properties of nanomaterials such as high electrical conductivity, better shock bearing capacity and the sensitive responses. These responsive fields such as piezoelectric and adaptable colour based identification systems were just a few products of exceptional nanomaterial properties. The nanobiosensors were outfitted with immobilized tests such as antibodies and chemical substrate. This thesis reports on characterizations and fabrications of biosensor based on graphene and metal organic framework (MOF-199) nanomaterials. Graphene and a mixture of graphene with MOF-199 with 9.4 wt%, 20.9 wt%, 22.4 wt% and 23.3 wt% were used as the nanosensor materials. Each mixture were then spin coated at three parameters from 2000 rpm, 2500 rpm and 3000 rpm respectively on Indium Tin Oxide (ITO) glass. The nanobiosensor were test with electrical conductivity Test, Scanning Electron Microscope (SEM), Energy Dispersive X-Ray (EDX) and X-Ray Diffraction Analyses (XRD). The electrical conductivity test, exhibited that the voltage increased after spin coating process from 26.1 mV to 31.2 mV for 2000 rpm as compared to 3000 rpm. The SEM result showed octahedrons shape of MOF-199 were maintained even after spin coating process and graphene addition. EDX showed that copper, carbon peak were from MOF-199 and graphene while Indium (In) was from the ITO glass. XRD analyses exhibited peaks from MOF-199 and graphene. 2024-07-24T03:54:53Z 2024-07-24T03:54:53Z 2017 Resource Types::text::Final Year Project https://irepository.uniten.edu.my/handle/123456789/32909 en application/pdf
