| Outline of Final Research Achievements |
Growth of single-walled carbon nanotube (CNT) from nanodiamond (ND) nuclei , non-metallic nanoparticle, was investigated to overcome the difficulty of very narrow growth condition and consequent low growth efficiency, resulting in demonstration of the advantage for practical use of high-purity CNT materials synthesized from ND. Single nm ND with very narrow size distribution was prepared by separation processes using high performance liquid chromatography. Driving force of CNT growth was optimized independently for the initial growth stage of CNT precursor formation and for the steady growth stage thereafter by adjusting the growth gas pressure and composition. Consequently, CNT growth efficiency was significantly improved to grow CNTs from very thin ND layer with narrow size distribution. Biosensor devices fabricated using high-purity CNT films grown from ND was shown to detect biomolecules selectively in very high sensitivity and wide range of their concentration.
