Abstract

Carbon nanotubes exhibit strong fluorescence emissions in the region of near infrared regions where most biomolecules are transparent. Such signals are highly sensitive to environment variations as well as adsorption of specific biomolecules. In this research, single walled carbon nanotubes(SWNTs) are assembled with different types of DNAs and used to target specific types of DNAs. Dot blot investigations and corresponding raman spectroscopy observations demonstrated excellent selectivity of carbon nanotube-DNA bioconjugates. The results show possibility of using SWNT as generic nano-bio markers for precise detection of different kinds of genes.
