CNT Electrodes Begin to Show Their Potential

摘要

Carbon nanotube (CNT) electrodes are revolutionizing electrochemistry to the extent that papers on the subject occupy three positions in the current Hot Ten: paper #2 reports their use in the analysis of cyctochrome c; paper #5 does the same for NADH; and paper #10 reveals a superior method for making them. In the past this last aspect has been a difficult challenge because it is almost impossible to coat a surface such as a glassy carbon electrode with carbon nanotubes unless they are dispersed homogeneously in a liquid medium, ideally dissolved in a solvent, but such solvents are few and far between.
