Abstract
We made the open well biochemical analysis system using piled up Carbon nanotubes (CNTs) as the reaction fields on a porous glass substrate. The effects of the structures of CNTs and the surface activation using 02 plasma to the sensitivity are evaluated. In this study, the reaction fields of CNTs piled up layer of 0.2 [mg] showed twice higher sensitivity than that of 0.1 [mg], and three times higher sensitivity than reaction fields of plane Si wafer. 02 plasma irradiation after making the CNTs reaction fields also increased the sensitivity of this open well system of biochemical analysis. These increases mean more absorption of proteins on the CNTs reaction fields, and that can be caused by the larger surface area of CNTs and the activation of CNTs surface.
