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 …
