dc.description.abstractNanotechnology and nanoscience research, control, manipulate, and assemble nanometer-scale components into materials, systems, and devices that meet human interest and needs. The rapid progress of nanotechnology and advanced nanomaterial production offer significant opportunities for designing powerful sensing devices with enhanced performances. Such nanomaterials may exhibit different properties and functions from bulk or macroscopic versions. In addition, these nanostructures can be suitable materials that favor integration with biomaterials or biological systems. In this context, carbon-based materials are being used as new materials with enormous potential for bioanalytical and biosensing applications. Accordingly, the main aim of these studies is to establish a detection technique to detect target molecules using carbon-based nanomaterials. Chapter 1 discusses synthesis methods that lead to successful production of functional carbon nanotubes (CNTs). Low pressure-chemical vapor deposition (LP-CVD), which facilitates the control of amorphous carbon to attract high spinnability, produced directly spinnable CNT rugs up to 600 mm or more. Chapter 2 focuses on the production of biosensors based on functional carbon nanotubes. In this study, Botulinum neurotoxin (BoNT) was used to experimentally demonstrate the application of CNTs to biosensors. We used a field-effect transistor with a p-type channel and electrodes along with a channel comprising aligned CNT layers to detect the BoNT. Finally, chapter 3 introduces sensing technology that utilizes graphene, which is one of the most prominent carbon nanomaterials. Paper-type devices utilizing multilayer graphene produced from pencil drawing capable of avoiding the rigid process of monolayer graphene and capable of manufacturing at low cost have been actively studied. Here, hydrogen detection was realized by applying palladium nanoparticles, which act as catalysts for hydrogen detection, to electronic circuits printed on paper using a metal mask and a pencil. We hope that our work will contribute to the development of molecular detection technologies using a variety of carbon-based materials.-
