A carbon nanotube forest is an array of carbon nanotubes vertically aligned and entangled. Because the aspect ratio of each tube can be more than 1000, the forest will greatly increase the number of potential binding sites on the surface for chemical and biological detector applications, if each bundle of tubes can be functionalized with specific molecules. The 1,5-diaminoaphthalene can be a versatile linker molecule for proteins. In this study, we characterize the concentration of 1,5-diaminoaphthalene in solvent by fluorescence spectroscopy. It appears, however, that the solvent collapses the carbon nanotube forest, resulting in no detectable fluorescence emission. Lithographically defined carbon nanotube forests patterns or chemical vapor deposition of the linker molecule could resolve this problem.
