The detection of a single nucleotide polymorphism (SNP) using single-walled carbon nanotube (SWNT) fluorescence is demonstrated for SWNTs coated in a probe DNA sequence (see image) via a fluorescence-energy increase of only 0.8 meV upon addition of the complement containing a SNP. This mechanism is simple, label- and enzyme-free, and the properties of the probe DNA that enable this detection are examined.
