Abstract

We demonstrate visualization method of carbon nanotubes (CNTs) in water with fluorescent microscopy through quenching effect that cause a decrease of fluorescent intensity around CNTs. Reversal contrast in fluorescence imaging of the CNTs was observed in fluorescent dye solution. We could observe CNTs under a constant excitation light for more than ten minutes. Dielectrophorctic force was used for CNTs deposition onto electrodes that consist of transparent conductive film. Scanning electron microscope revealed that CNTs of 80 nm in diameter were observed with fluorescent microscopy. The positions of the CNTs tips were observed under optical microscope. It can be applied for biological sensing devises with nanomanipulation.
