Carbon Nanotubes Reaction Fields for Open Well Biochemical Analysis System

Abstract

We made the open well biochemical analysis system using piled up CNTs as the reaction fields on a porous glass substrate. The effects of the structures of CNTs and the surface activation using O2 plasma to the sensitivity are evaluated. Reaction fields of CNTs layer of 0.2 [mg] showed twice higher sensitivity than that of 0.1 [mg], and three times higher sensitivity than Si wafer. O2 plasma irradiation also increased the sensitivity of this open well system of biochemical analysis.These increases can be described as the results of the larger sorbable surface area of the reaction fields.
