Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

... a liquid or in air. "When the DNA portion of the nanosensor binds to a target molecule, there will be a slight change in the electric charge near the nanotube," Johnson said. "The nanotube will then pick up on that change, turning it into an electric signal that can then be reported." According to Johnson, a...

New nanosensor uses quantum dots to detect DNA

...cer. The Johns Hopkins team described the new DNA nanosensor in a paper published in the November 2005 issue of the journal Nature Materials. "Conventional methods of finding and identifying samples of DNA are cumbersome and time-consuming," said Jeff Tza-Huei Wang, senior author of the paper and supervisor o...
