Abstract
- A novel luminescent Eu3+complex functionalized single-walled carbon nanotube (SWNT) was constructed by covalent linkage through a diaminotriethylene glycol linker. TGA, FT-IR, and SEM demonstrated successful attachment of the Eu3+complex onto the SWNT surface. Spectroscopic methods showed that the SWNT-Eu3犉ꦕ is highly luminescent and DNA can further enhance the red luminescence, and the enhancement depends on DNA sequence and form. The order of the enhancement follows: AT alternative dsDNA > nonalternative AT dsDNA > GC dsDNA > ssDNA dA > ssDNA dT > ssDNA (GT)20. [ABSTRACT FROM AUTHOR]
