Detection of DNA on nanotubes offers new sensing, sequencing technologies

ons in medicine, microbiology and environmental science," said Esther Jeng, a graduate student at Illinois and the paper's lead author. "For example, this system could be used in genomic screening to detect sequences that encode for genetic disorders, and that are precursors to diseases such as breast cancer."

"Optical detection allows for passive sensing of hybridization, meaning there is no need to pass voltage or current through the system," Jeng said. "Furthermore, optics yield high-resolution signals and require a relatively simple setup. And, because our detection setup is in solution, we can sense in a natural biological environment."
