Nanotube impants show diagnostic potential
Nature News - 08/21/2015
Preliminary experiments in mice, reported by scientists at a meeting of the American Chemical Society in Boston, Massachusetts, this week, suggest that the devices are safe to introduce into the bloodstream or implant under the skin. Researchers also presented data showing that the nanotube–polymer complexes could measure levels of large molecules, a feat that has been difficult for existing technologies.
“Combining carbon nanotubes with these attached templates imparts the unique ability to detect larger molecules, which has been challenging because we don’t have good tools for recognizing them,” says bioanalytical chemist Heather Clark of Northeastern University in Boston. Although it is important to thoroughly investigate the sensors’ compatibility with the human body, she notes that “as this exciting technology moves forward, it will be interesting to learn more”.
