Detection of DNA on nanotubes offers new sensing, sequencing technologies
Date: 8.3.2006
Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences.
Potential applications for the new sensors range from rapid detection of hazardous biological agents to simpler and more efficient forensic identification.
In the Jan. 27 issue of the journal Science, chemical and biomolecular engineering professor Michael Strano and his students reported that single-walled carbon nanotubes coated with DNA could be placed in living cells and detect trace amounts of harmful contaminants. In a paper accepted for publication in the journal Nano Letters, and posted on its Web site, the researchers report they have taken the technique a significant step further.
