摘要：
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 via a fluorescenceenergy 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. (Figure Presented). © 2010 WILEY-VCH Verlag GmbH & Co. KGaA,.
