Abstract
In this study, carbon nanotubes (CNTs) are anticipated as nano/micro structured reaction field for micro Bio-Analysis. CNTs reaction field were made on quartz glass substrate using chemical vapor deposition and Self-Organization of CNTs. To evaluate and reveal the optimal structure of CNTs structure, protein adsorption characteristics were evaluated by fluorescence and transmitting spectroscopy analysis. By fluorescence analysis, it is revealed that proteins tend to adsorb to tip of CNTs structure and finer structure. Finally, protein adsorption was detected as a change of transmissivity of CNTs reaction field, and its detection limit was about 100 nmol/l. Time for analysis was greatly shortened by using transmitting spectroscopy.
