Mediated Electron Transfer at Vertically Aligned Single-Walled Carbon Nanotube Electrodes During Detection of DNA Hybridization
Vertically aligned single-walled carbon nanotube (VASWCNT) assemblies are generated on cysteamine and 2-mercaptoethanol (2-ME)-functionalized gold surfaces through amide bond formation between carboxylic groups generated at the end of acid-shortened single-walled carbon nanotubes (SWCNTs) and amine groups present on the gold surfaces. Atomic force microscopy (AFM) imaging confirms the vertical ...
متن کاملOptical characterization of vertically aligned single-walled carbon nanotube arrays
Here we discuss spectroscopic investigation and characterization of vertically aligned single-walled carbon nanotube (VA-SWNT) arrays, which were synthesized using the alcohol catalytic CVD method [1]. Growth of the VA-SWNTs was monitored using an in situ absorbance measurement [2], which provides information about the growth process. Primary methods employed were Resonance Raman and UV-Vis-NIR...
متن کاملAnisotropic electrical conduction of vertically-aligned single-walled carbon nanotube films
Anisotropic electrical conduction measurements have been carried out for thin films of vertically-aligned single-walled carbon nanotubes (VA-SWCNTs) grown by an alcohol catalytic CVD process. Combined with controlled synthesis and structure characterization by optical spectroscopy, the influence of the aligned structure on the electrical conduction has been identified. The out-of-plane conducti...
متن کاملMultiple “optimum” conditions for Co-Mo catalyzed growth of vertically aligned single-walled carbon nanotube forests
Carbon nanotubes (CNTs) were grown directly on substrates by alcohol catalytic chemical vapor deposition using a Co-Mo binary catalyst. Optimum catalytic and reaction conditions were investigated using a combinatorial catalyst library. High catalytic activity areas on the substrate were identified by mapping the CNT yield against the orthogonal gradient thickness profiles of Co and Mo. The loca...
متن کاملThe internal structure of vertically aligned single-walled carbon nanotube films
In this study, we investigated the internal structure of ’as-grown’ vertically aligned single-walled carbon nanotube (VA-SWNT) films by cross-sectional transmission electron microscopy (TEM). The VA-SWNTs were produced by the alcohol catalytic CVD method [1, 2], and transferred onto a TEM grid using a hot water technique [3]. The resulting freestanding VA-SWNT film was observed along the alignm...
