dc.description.abstract | Due to their small size and remarkable electrical properties, carbon nanotubes have been used to
modify electrode surfaces to create sensors for a range of important analytes. In this study, glassy
carbon (GC) electrodes modified with films of HiPCo? single-walled carbon nanotubes (SWCNTs)
were prepared by drop-coating dispersions of the nanotubes. A number of different solvents were
evaluated for this purpose. Atomic force microscopy was used to show the porous nature of the
nanotube assemblies. The modified electrodes were used in the determination of dopamine and
epinephrine, and compelling evidence of thin-layer mass transport regimes within the porous films was
observed using cyclic voltammetry. The work described here exposes some potentially flawed
arguments commonly made in the literature regarding the `catalytic? properties of nanotubes. We
believe that the issues raised must be addressed if the much-promised applications of nanotubes in
sensor devices are to become a reality. | en |
