시료용액의 특성에 따른 고정화된 단일벽 탄소나노튜브의 전기적 거동 = Electrical Property of Immobilized SWNTs Bundle as Bridge between Electrodes in Nanobiosensor Depending on Solvent Characteristics

다국어 초록 (Multilingual Abstract)

In recent, it is worldwide issued that nanoscale science and technology as a solution have supported to increase the sensing performance in carbon nanotube based biosensor system. Containing material chemistry in various nanostructures has formed their high potentials for stabilizing and activating biocatalyst as a bioreceptor for medical, food contaminants, and environmental detections using electrode modification technologies. Especially, the large surface area provides the attach-ment of biocatalysts increasing the biocatalyst loading. Therefore, nano-scale engineering of the biocatalysts have been sug-gested to be the next stage advancement of biosensors. Here, we would like to study the electrical mechanism depending on the exposure methods (soaking or dropping) to the sample solution to the assembled carbon nanotubes (CNTs) on the gold electrodes of biosensor for a simple and highly sensitive detection. We performed various experiments using polar and non-polar solutions as sampling tests and identified electrical response of assembled CNTs in those solutions.
